I have Forticlient, only the AntiVirus part, on 64 bit Windows 7.
Since that moment, setup and operation of certain programs fails with the error: "the requested operation cannot be performed on a file with a user-mapped section open"

On the internet I found several references that this can be caused by antivirus software.
So I tried disabling the FortiClient RealTime Protection, and this indeed solves this, but this is not really an option.

Other antivirus software I tried does not have this problem, but I would like to use FortiClient.
(Because it's free for business use)

Anyone an idea how to solve this?

(I have seen this on three different 64 bit Win7 machines, never on any 32 bit OS)
