Left4Dead2 Visuals Multihack

[redogg]

should look like this, then you have to go to 'Steam\steamapps\common\left4dead2\bin' and delete libcef.dll

Now it opens a Window, but then it crashes. I'm using the Vr.dll for nonsteam (cause I have the nonsteam L4D2) but before opening the L4D2 it appears 3 exact erros, talking about "chromehtml.dll". But the thing here is, it opens a Window and then crashes.

i think you might have done something you didnt need to. since you nonsteam you cant verify your gamefiles, try to redownload the game to restore all the files to default state, after that do what @Lorian told you and it should work just fine
however, does unknowncheats version work for you?
