Issue
When trying to log into Workstation you get "Access is denied".
Environment
- Vista
- Workstation
- Windows 10 (not supported)
Cause
First verify that the licensing is installed and working properly on the machine. If running Vista on a Windows 10 machine and the message "Access is denied" still appears when logging in to Workstation then there may have been Windows updates applied to the PC causing the issue. Microsoft has identified an issue with their updates and have plans to correct them in future updates.
Note: Windows 10 is not a supported operating system for TAC Vista.
Resolution
If using Windows 10 with TAC Vista, then check to make sure that the following updates have not been installed (updates depend on the Windows 10 build being used). If one of these builds have been identified then remove the Windows Update and restart the PC. After the reboot, the operator should now be able to log in to Workstation.
