The mod is a bit complicated to Install two others mods
Bootstrap and Shared import : I took the liberty to include the files in the zip files . so you don't have to download those necessary from anywhere else and the lign you needed to write is already written. 

1 : Place modBootstrap, modRandomEncounters and modSharedImports in your mods folder..   

Note : ( you don,t need to install theses files if you already installed them, as they will conflict)

2 : place DLCBootstrap and DLCRandomEncounters in your dlc folder. its in the same folder as the DLC 1-16, Heart of Stone (ep1) and Bloodwine (bob)

3 : find your Input files  and under [Exploration] and [Horse] place the following lines  ; IK_9=(Action=RefreshRESettings) AND IK_0=(Action=RandomEncounter)

4 : Copy the randomEncounters.xml Files in modRandomEncounters\bin\config\r4game\user_config_matrix\pc   ....  And paste it in your bin\config\r4game\user_config_matrix\pc\   File.. 

it should appear with other Xml files. 
5  Modifying the Random mods setting in your game how you like, then press 9 to save it. 

6 and if you are too impatient to play the game or to find these encounters, press 0 

Honestly. if it work find on my PC..  that should be fine for U. okay, sometimes I have strange impressions. but everything is working.
