Hej Guys, i have the same problem... i try to follow your explanations.. but my english isnt that good, sry. " Original Skyrim (a.k.a. Legendary Edition) uses TESV.exe. The game directory is in steamapps\common\Skyrim.Skyrim Special Edition uses SkyrimSE.exe.The game directory is in steamapps\common\Skyrim Special Edition" I bought Skyrim long time ago and after some time i got all the dlcs too. No Skyrim Special Edition (, but maybe the Legendary Edition cause of all DLCs?). The file name is called TESV.exe besides my SKSE.exe Version i dled. I tried to dl some mods from Nexus for my gameplay, skyrimSE webside. So do i have to dl the mods of the original normal skyrim webside and the mods dled will automatically turns to the 'SE' version, because as i said i have all of these DLCs??? Nexus Mod Manager acutally show up my heartfire, dragonborn, dawnguard etc. plugins. And further do i get any problems and crashes if i install normal old skyrim mods via nexus mod manager due to my Skyrim with all all dlcs when i go inplay for dawnguard areas and questline ...
