Hi everybody! I just downloaded DriveSentry, tried installing and i'm getting this message: DriveSentry requires the Filter Manager please install the latest Service Pack for this Operating System. After that the installation seems to continue but at the end i get another message saying it can't install because i have another antivirus.(which is true, i also have Avira Premium but the guard was deactivated when i tried installing) Also from what i understood, they should be compatible. My OS is Vista Business SP1 64 bit. All updates are installed. So, if anybody knows how to fix this problem i would really appreciate it.
