The error message indicates that one of your avast! file is missing or corrupt.
Try the repair of installation as that should replace the problematic file.
Nope i’ve re-installed/reformatted a few times and avast still conflicts with sandboxie…sandboxie works fine until I install avast!
The last thing I want to do is not use avast anymore, it’s my fav free av, but I also love sandboxie so why can’t they co-exist?
Well no problem here with sandboxie 6.32 and avast! free 6.0.1367 on my win7 (32bit) netbook.
I have made no changes in the avast settings for sandboxie, but sandboxie detected, ObjectDock, avast! antivirus and 7-Zip Shell Extension in the Sandboxie Control - Configure - Software Compatibility, section so perhaps you need to check that as nnoa110 mentioned. I had never ventured into that sandboxie software compatibility before.
I’m only using it on my browser, firefox 9.0.1 though.
One of the other things to look into are the other services that can’t be started I don’t know if there is some dependency thing going on here that the avast sandbox also requires.
Whilst you say you have snxhk.dll in that location that doesn’t mean that it is running, so I don’t know if using the rundll32 command - rundll32.exe snxhk.dll to start it. I don’t believe you need to enter any paths.
