On 7/31 I upgraded from ZA Internet Security to Extreme Security. Everything was working fine, but a few days later when shutting down Windows Update installed a patch. The patch install hung and I killed it after waiting 7 hrs. I logged in and eveything seemed ok, ZA was working fine. Upon shutdown, the patch installed and this time finished.

Next time I logged in I got the error message: Validation failed for C:\Windows\system32\VSINIT.dll. You probably are missing a necessary root certificate.

I uninstalled ZA Extreme Security based on recommendations and now when I try to reinstall I get the following error messages and the install fails: Installer failed to initialize. Please try to download and run the installer again. When I click OK on the error, I get the following error message: Could not load the DLL library
C:\DOCUME~1\steve\LOCAL~1\Temp\081020222459\vsutil .dll
(ls64bit).The specified procedure could not be found.

Interestingly, MS Security Center says that Extreme Security reports that the Anti Virus and Firewall are working fine, but it is not installed.

Any ideas how I can get the product installed again?
