Issue
- Can't log in to Vista Workstation.
- The following error message occurs: "An unhandled Microsoft.net Framework exception occurred in TACVistaExplorer.exe[5420]"
Environment
- TAC Vista 5.1.5
- Windows XP
Cause
This can be caused by the regsrv32.exe not functioning correctly. Regsrv32.exe is a Windows program task that registers programs into your system registry. This causes problems during the installation of Vista as certain parts of Vista will not be registered correctly.
Resolution
The following can be checked in an attempt to correct this fault:
- Check the %systemroot%\Windows\System32\ catalogue to see if the regsrv32.exe file exists.
- Check that it is spelled correctly and that the file type is .exe.
- After correcting these 2 points reinstall Vista.
