Reverting to an older version of Vista / Downgrading Vista
TAC Vista Server IV
Typically done on an engineering PC, downgrading a version of Vista can result in problems since this is not a practice that is rigorously tested.
- When restoring a previous version or downgrading Vista the first thing to do is to delete the TAC Shared Folder (Program Files/ Common Files/TAC Shared).
- After the directory is removed then run the older version install files.
- If you are using Vista 4.3.0 or higher, be certain that your Computer Name in Instance field of Server Setup/SQL Server is correct, (ComputerName/TACVISTA).
- You can test the SQL connection to verify it is correct after the installation is complete.
