Thanks for the reply. Appreciated.
I tried these two procedures: Click to clear the "Check for server certificate revocation" option 1. Start Internet Explorer. 2. On the Tools menu, click Internet Options. 3. Click the Advance tab. 4. Browse down to the Security section. 5. Click to clear Check for server certificate revocation, and then click OK. 6. Restart the computer. Advanced user steps: Register Softpub.dll, Wintrust.dll, Initpki.dll, and Mssip32.dl 1. Click Start, click Run, type regsvr32 Softpub.dll, and then click OK. 2. Repeat step 1 for the following files: Wintrust.dll Initpki.dll Mssip32.dll The first procedure was simple but did not resolve the problem - still could not update. The second procedure ran nicely with regsvr32 Softpub.dll. However, when I ran regsvr32 Wintrust.dll I got another error window pop up:
"The module "Wintrust.dll" was loaded but the call to DIIRegisterServer failed with the error code 0x80070005." Initpki.dll
also failed; but Mssip32.dll
As I said, I'll keep hunting. Thanks for the help.
