Just curious about the prefixes and how they work specifically.

Been doing some reading and know enough that it depends on the system variable...

[program files] in SEP = %programfiles% in the system

My question goes more to a 64-bit system where the is Program Files and Program Files (x86).  Is this accounted for in any way or will it be stuck to just Program Files, where everything in Program Files (x86) is not excluded?

I am trying to create an application exception for CA ArcServe and they seem to have files in both paths, and the exception created does not seem to work.  Therefore, I want to get a better understanding of it.  If it is not able to compensate for both, then I will need to use the specific paths or even go as far as excluding the entire CA directories.  Any thoughts or advice would be great, since the backups went from running 9 hours before SEP 12.1.2 to 14+, so SEP is obviously stepping on something.

In the past, the system was running SEP 11, with AV only, no PTP, IPS or NTP installed.

Thanks
