When I get the the end of the install process for the latest version of PGP Desktop Home 9.0, the installer asks me to reboot. Upon starting up, my system has major problems starting up. I get a svchost.exe error (instruction at 0x7c809784 referenced memory at 0x00000010, memory could not be written" just at the welcome screen (seemingly before logging onto the OS). Often this error is repeated, the system takes about 15 minutes to start up (much more than the 2-3 minutes normal), most other applications fail to start (with various errors), and I eventually get a "windows must restart" because the RPC service terminated unexpectedly. My primary avenue of recovery is to start in safe mode, and do a system restore before the installation of PGP.
Tech support at PGP thought the error was due to a spyware conflict. I ran AOL spysweeper, SpyBot S&D, Ad-Aware, and Microsoft's AntiSpyWare (beta 1), which found various things, but not fixed the problem.
I have the very latest critical and security updates of XP home SP2 and McAfee VirusScan (which finds nothing).
I also tried clean installation (with load startup items unchecked, all non-Microsoft services unchecked, and system.ini and win.ini unchecked in msconfig). That doesn't work. No helpful errors appear in the event log.
I downloaded the PGP application file again (in case the first was corrupted), to no avail. I asked if the earlier version of PGP was available, but was told "no."
Of course, the simple answer is "don't use PGP," but I have a client that insists on it. Any other troubleshooting or installation tips would be appreciated.
