Running Process Guard 1.200 on WinXP Pro. Sysinternals Regmon and Filemon utilities require drivers to work, so I have them in my PG list, with the "Allow Drivers/Service Install" option enabled for each. Of course, I also have the "Block Drivers and Services from installing" option enabled. The problem is that Filemon and Regmon can't load their drivers, even with the "Allow Drivers/Service Install" option enabled. Sysinternals coded for this type of error, and upon trying to launch either utility, an error appears which says "The system cannot find the file specified". (This error appears because Filemon and Regmon create and load their drivers dynamically; they actually create and register their SYS files on the fly on each run.) If I simply disable the "Block Drivers and Services from installing" option, Filemon and Regmon work fine (without so much as rebooting). A bug in Process Guard?
