Hi,
Are you running (or trying to run) VeSys 2.0 in the Evaluation mode? If true, then we have experienced some problems with some security software that still needs to learn that VeSys is safe, so we will follow-up on this. Can you confirm which version of VeSys 2.0 you tried to install and also what version / details of McAfee you have.
In the mean time I suggest you contact your vendor, who should arrange for you to have a loan license (rather than using this Evaluation mode).
Kind Regards,
Nuri
