CIS 3.8 blocks almost all .exe files on Vista x64

I have same problem CIS 3.8.65951.477 with Nod32 Antivirus 3.0.684 in Vista x64.
Only CIS 3.5.57173.439 works fine. All versions after 3.5.57173.439 I tried have same bugs.

Now, I’m trying to install CIS 3.9 Beta…

There is a newer version out; a Release Candidate: https://forums.comodo.com/beta_corner_cis/comodo_internet_security_3974913496_rc1_released-t38361.0.html .

When the problem is still there with the RC submit it in COMODO Internet Security 3.9.74913.496 RC1 Bug Reports. Please read the first post on how to submit your bug in this topic.
