SimPE finds the folders automatically by relying on the registry, which the steam version doesn't create, but the steam version doesn't have that of course, so you have to modify these file tables from an xml file.

Overwriting this folders.xreg file with the one in the Data folder (which should already have folders.xreg) will fix the file table.



If it's installed in another directory, change all occurrences of "C:\Program Files (x86)\Steam\steamapps\common\The Sims 2 Legacy Collection" to the directory of your game.



If you want to load your neighborhood, change the SaveGame value to C:\Users\<your name>\Documents\EA Games\The Sims 2 Legacy.
