Security update for Nexus Mod Manager

  • Comment

Today we are releasing some security updates for the Nexus Mod Manager to bring us in line with the new EU GDPR rules coming into force next month.

NMM has been "end-of-line" since 2016, which means we no longer provide any official support for the software, but we thought it was prudent to spend the time and money to release this update so our users could continue to use the software's online services while ensuring we're compliant with the new regulations. We also did not want people to think we were using the GDPR as an excuse to force people on to our new mod manager, Vortex, either. The alternative was to simply turn off the old services completely, essentially making NMM, and any other software using our old login services, offline only.

To prevent any drama with this process, we've even patched up version 0.52.3 of NMM (the last version before the profile functionality was added) so there are no complaints.

In order to be compliant, we need to turn off our old, less secure login to the web services completely. We plan to do this on Tuesday the 8th of May. This will mean anyone who does not update their NMM will no longer be able to use NMM online. This will prevent you from being able to login, check for new file versions or download mods from the site directly in to NMM. This will also affect any other software that uses the old login destination and method, for example, Mod Organizer. We do not officially support Mod Organizer, nor is it made, updated or maintained by us, so any updates needed to ensure it works with our new login service will need to be handled by the team behind Mod Organizer. If you are currently a coder with software making use of the old Nexus login system, please do get in contact via PM or Discord and I will put you through to the appropriate person to help you get on to the newer system as soon as possible.

For convenience, both updated versions of NMM can be found on a new file page setup to make this a little easier. Remember, download 0.65.0 if you are using a version of NMM that is 0.60.x or later. Download 0.52.4 if you are using version 0.52.3 of NMM.

Apologies for the inconvenience caused, but it's 8 year old code now and, at some point, this was going to happen!

    Smells like "Open Ended Tool Suicide" orders to me. Based on the layout of 'Vortex', it seems all's not well because it's not ending well... the age of simple and useful tools for the general public is bought out by flashy animations and Steam Gaming. I will hope not to be phased out by all of this... and as far as updating my NMM, comments make it clear it's likely to be just as painful as the last 3 times I tried to update it. Manually importing mods through my current version of NMM for now, it is the new norm.

    My head is spinning from all of this...

    I'm going to have to ask some potentially dumb questions in order to sort this out in my head.

    1) Have people actually gotten Mod Organizer to work with the new login fix?

    2) Is the login fix specifically for the Mod Organizer that handles regular Skyrim? as in Non Special Edition.

    3) Have people found issues with MO even after using the login fix? Or is the fix "Do and forget"? this question is directed at those with heavily modded games.

    I'm looking for a way to continue modding without being hit with unforeseen errors out of nowhere that I'm not going to be able to understand and fix by myself, I've read as much as I can stand on this thread, everytime I think I've found a fix, someone has come back and said that it's unreliable or doesn't work or whatever, I hope you can all understand my frustration here, but I'm fed up with it, the thing that was once a fun hobby of mine has now turned into a "Vortex" of confusion, mixed information, and a bloody nightmare in general.

    I'm not a tech savvy individual, so when I get errors that sound along the lines of "Exception has been thrown by the target of an invocation." like what I had with NMM before I deleted it, my god...Wow! how does Microsoft expect anyone to fix their own problems with insane techno babble like that, that sentence doesn't even make sense for god sake. *Facepalm*

    Anyway, sorry for the rant, but please help me understand what I'm doing, I feel like my brain is broken right now, everytime I get myself pumped up to tackle starting over with a new manager, so much uncertainty gets in the way. (x_x)

    P.S

    I have even tried Vortex, to see if it was as simple as Gopher makes it sound, but I quickly found it beyond me in its current state, it needs a drag and drop system for its load order which currently it doesn't have, instead, you have to jump through hoops, telling the manager where to load mods and their masters via a kind of "Connect the dots" way, which gets quite head spinny after a while.

    When it says something is conflicting, it doesn't seem to tell you exactly what "Specific" file it's conflicting with, only the whole mod and the number of conflicting files, so I found myself just sitting there, wracking my brains as to what the problem might be and if it would cause problems at all, as I stared at this red thunderbolt symbol telling me there's a problem with said mods that I "Needed to resolve" to quote it's wording, making it sound more urgent then it actually may have been.

    Either way, I'm gonna wait on that one for now, I disabled the mods I had enabled in Vortex, then checked to see if it had properly removed the files from the data folder, and it did not, the Caliente file from Bodyslide was still there as well as others, so I just deleted the data folder and verified game cache to get the essential game files back, consider this as your warning of Vortex's current shenanigans lol.

    Thank you very much.  I will look into that later today.  I do thinki that at least two of the Mods I am running require at least 0.53 so I will check and see if I have anything else that lists a more recent version.
     
    -----   Much appreciated

    For roughly two weeks I have tried to either enter NMM to update or using sign in credentials,after I add my PW, absolutely nothing happens.I have tried adding the new NMM patch fix, and still nothing.I run my Gaming PC on Windows 8.1

    ---- I suppose for myself at least until the Vortex can be considered reliable for the common gamer to use, that I am out of luck in being able to access any additional Mods from the Nexus.Very much a shame this is happening.I have felt that the Creation Club with bethesda has already diminished the flow of creative juices for mod creation anyway. "Forever Free" within the mods and assets; was a pioneering spirit that felt as if the entire modding community as a whole was unified and each empowered on equal footing.While I am glad that some of the very devoted and talented Modders have gotten their opportunity to see some additional financial benefits from their work, I will admit that I no longer refer Gaming Friends to the Nexus now in casual chat, not in the way I used to gush about how wonderful it was here.I have never wanted to seem unappreciative of the great work and dedication of the Nexus in having a fantastic place for modding creations to find a home; but in all honesty, for myself at least the overall site design now and the recent changes overall, have left the feeling of a more sterile and cold place. I know very well of the need to have some changes take effect in how the site can be accessed due to the EU enacting the new GDPR; a law to cover privacy issues with companies that do business that collects any myriad number of potential Personal Identity information, and that same law then expands to cover any businesses that do business with companies in the EU.So basically, if you are having an online presence at all, you are affected.

    ------ So right now I am continuing to look for some directions to allow me to still use NMM for the short term, and if, I then still retain enough desire to down the road to ever work with adding Mods to a game again, I will of course check out Vortex.But after reading about a lot of current issues with Vortex, its simply a matter of balancing my level of need to go through a lot of hassle to add a new app to manage Nexus mods, versus my desire to try new things with Games I have already played through 3 or 4 times (at least), and have been just revisiting for a playthrough using what new MODS and setups I can add. Since I can't add more mods now, its giving more a sensation of "buzzkill" right now.But I do very much hope that I can find a solution soon, and re-kindle my interest.

    -------------I respect the post at the Info intro for this Topic, and yes, the NMM may be 8 year code, but then again, the same could be said of Skyrim and Fallout:New Vegas ( which is what I was playing through again).So at least for the good feels from the past 5 years since I got into Modding, Thanks for those memories. I doubt their like shall be experienced again. But it was a wonderful time :)

      Get version 0.56.2. This one works with all FO3/NV mods I've tested and does not have a virtual file system which is a good thing for UIO-based New Vegas mods.

      Caveat: you may be required to reconstruct your mod list after changing NMM version.

    Why would you remove support for the Nexus Mod Manager? Just recreate it under a new code but, with the same simplistic layout and look. Vortex is just too glossy and has more things that are embedded in it. It gets confusing after a while..

    So I upgraded to the very last version of NMM as shown at the top of the nexus page, I can log in, but when I try to re-download a mod it gets an error saying...

    An exception occured in the script.

    I click show details and it says something roughly to this effect...

    System.Reflection. TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.EnvironmentPermission,mscorlib, Version=4.0.0.0, Culture=neutral, PublicKey Token=b77a5c561934e089' failed.

    Then goes into an endless torrent of other computer jargen under the heading of "Server stack trace:".

    I have no clue what any of that means, but I tried opening NMM as an administrator and it persists, so whatever it means by permissions has nothing to do with being an administrator I guess, does anyone know what it means? if I can't get NMM to work anymore, I'm happy to try a different mod manager, but I need to know that it works well, I don't know what's happening with Vortex and what is being done with it, how stable it is.

    I could try Mod Organizer, as long as it can download mods from nexus just as stably as NMM, I've seen the MO fix on this page yes, I just want to know others opinion of other managers before I decide, I've never used anything but NMM before, so it's a scary undertaking, learning a new Manager, your thoughts are appreciated.

      Is there a way to fully uninstall NMM? I tried installing the one from your link @Caduryn but the error persists, I suspect installing over the original didn't work, I need to purge the system of anything to do with NMM before installing your version, just to be certain there's nothing else preventing it from working.

      I'd like to echo Caduryn that the github version 65.4 seems to work well. I had several issues after the EU-forced update for 65.2. Examples included not being able to sort mods and also not being able to install FOMOD-menu mods. 65.4 seems to have this corrected. Unfortunately, the only way I know of to COMPLETELY uninstall NMM would be to find every directory, including those in your User folders as well as the Fallout 4 folders and delete it all. At that point, heck, I'd just uninstall and reinstall Fallout 4 completely. Sorry to hear that you're having these issues.

      v0.65.4 works in some cases, but is not 100% reliable. There are valid install scripts that continue to fail with v0.65.x. The problem has been reported over at GITHUB, and will likely be resolved eventually.

      Forgive me for being uneducated in this whole deal, but if I install the version from that link, will it automatically replace my old version and keep all of the mods there? Or will I have to completely uninstall NMM before installing that one?

      @Reldnahc98 That's the mystery that basically led to my problems, I would wait for more info before doing anything, lest you meet the same fate as I lol, by the time I heard about the github version, I had already tried both "So called" "Fixed" versions of NMM released by Nexus team, 52.X and 64.X only for them to make matters worse, so I don't even know if upgrading to github version would have solved my problem or not. :/

      Then there's what Athelbras says above... so I really don't know, we might all just have to migrate to MO, those of us who couldn't get NMM to keep working, the Vortex page makes it very clear that it is in Alpha stage, so dunno what the deal is there.

      From what I remember, NMM has been in Beta since release, (at least it has been since I began modding.) and I never had major issues with it except the occasional messy uninstall on a mod I had to manually clean, if Nexus team has indeed improved on their original Manager idea than I can't imagine what issues Vortex would have that NMM didn't.

      Oof, this has just become a confusing problem for everyone, it seems. I think my best bet would be to wait a while for a concrete fix. I can still play my games with my current mods so waiting isn't that big of a problem; still, though, I like for all my software to be updated and I've been itching for a couple new mods I've been looking at.

      @Reldnahc98

      I reckon you'll be waiting a while unfortunately, Dark0ne said that NMM has been discontinued basically, so unless someone takes it upon themselves to go into NMM's code and improve upon it, (Assuming Nexus Team allows that.) NMM is dead my friend, from this point it's either change Managers, or don't use any new mods.

      It's looking pretty grim, I know that feeling of dread tho, this'll be the second time I have to redo everything, and the damage is already done in my case. :/

      Either way, I feel like the only way to know for certain that your manager continues to do it's job in future will be to purge all things NMM from the system and start from scratch with a new manager, at least then if you get problems, you'll know it isn't because of this login business.

      I've always heard people swear by MO, saying it allows for much greater control over what happens with your mods, it's apparently more complex than NMM obviously, requiring you to have a certain "Awareness" of what files go where, but maybe it's worth looking into, I would take a look at some tutorials on how to use it, I probably will myself.

      Ouch... this sucks. I'm new to modding so I've a lot to learn. If I was to remove NMM completely from my system, download another manager, and install the exact mods I had before onto this new manager, would that keep my games' save files safe and sound?

      I had the same exception with the latest version of NMM when was trying to install SkyUI mod
      So, I had to downgrade it to 0.63.19, and now it seems to work.

      You can find it at github

      Theoretically yes, because all you will be doing is removing the mod files the save relies on, switching managers, then replacing them once again.

      The only serious ball-ache then is making sure your load order is the exact same as it was before the migration, the safest/easiest way I can think of is to take a screenshot of your load order, so you can re-arrange them after migrating, that way, in theory, it should be as if nothing was changed, as long as the game has access to the files that were present when the save was made. :)

      If you need help learning a new manager or with any other core aspect of modding I recommend watching Gophers modding tutorials, he has videos for both MO and Vortex now, I think I also saw some for MO2 which is the most updated version of MO I believe, Gophers videos are excellently paced for beginners and he explains things down to the smallest details. :)
