Antivirus installation error

For some reason the antivirus package that comes with Parallels does not want to be installed. Here's the error I keep getting (attached). Has anyone else experienced this? I have reinstalled Parallel tools several times, but nothing seems to work. I also attempted searching the Parallels disk unsuccessfully for an .exe file.

When I initially installed, I did have a hang-up with the install of Parallel tools and had to restart. I wonder it this is related. The program strikes me as very "buggy". I have used Crossover for Linux, and I had none of these problems.

Thanks in advance for the help.

 

Do you mean you used Crossover for Linux to install Parallels Internet security?
As for problem itself please create ticket in support , it seems to me that Vista installation is either corrupted, or it is Vista OEM
Anyway, it is a good idea to investigate situation closer
