I’m running Vista Premium on a Dell Dimension 9200 using Adobe Reader 8.1.1.It will not install updates or uninstall Adobe Reader–Error 1402 Could not open key. HKEY_LOCAL_MACHINE\Softwareclasses\CLSID\(D38064DA). Adobe will not provide tech help as it was a free download except for a lengthy instruction which involves fiddling with the Registry–which I dare not do.I could not find any reference in your archives.Thanks.
It sounds like something is tying up your Adobe installation. You may want to try starting the computer in Safe Mode and seeing if it is possible to uninstall Adobe that way.
If it isn’t possible, then disabling any Adobe products that are starting with the computer is the next step. You’ll need to open the System Configuration Tool and take the ticks off anything referring to Adobe in the Startup tab.
Finally, you could try creating a different administrative user and seeing if this repairs the problem.
If none of these work, you’ll have to call in a technician to fix the registry problem.
