We use the Crashplan backup software (which is fantastic, I might add) and PrevX Enterprise is killing the installer. We have customised the installer from Crashplan to apply our own settings, and as a result the installer auto-extracts some files into a temp directory. These files are named randomly and automatically, and PrevX is killing them when the installer runs. I've contacted support, but thought I'd post here as well in case anyone else has had issues between these 2 products. With the 126.96.36.199 version it's blocking the installer completing, and I don't even get an alert or scan history in the PrevX console. So... I can't even override it.
