Issue
Trying to upgrade to Vista 5.1.2 but the following error is displayed and the application will not install:
Unable to connect to SQL Server: (local)\TACVISTA ([0] Cannot generate SSPI context)
Product Line
TAC Vista
Environment
Vista 5.1.2 Server/Workstation Installation
Cause
When you first run the Vista 5.1.2 file it should uninstall previous versions of Vista, which it does but it does not uninstall the hot fixes.
Resolution
- Uninstall the Vista hot fixes through the add/remove programs in the control panel
- Run the TACVistaServer512 file again.
