Microsoft Visual Studio 2010 SP1 Beta will not install when ZoneAlarm Extreme Security 9.3.037.000 is installed.
I tried ShutDown of ZoneAlarm Extreme Security but install of Visual Studio 2010 SP1 Beta still failed.
An uninstall of ZoneAlarm Extreme Security was necessary before Visual Studio 2010 SP1 Beta would successfully install.
It seems that ZA shutdown leaves some memory resident component which is stopping MS Visual Studio 2010 SP1 Beta from validating the signature of one file (vs10sp1-KB983509-Pro.msp).
I'm using Windows XP SP3 with all current updates.

Has anyone else tried to install Studio 2010 SP1 Beta ?
