SQL Server 2012 Upgrade Advisor Needs a Separate Installation


For some reason, the option 'Install Upgrade Advisor" on "SQL Server Installation Center" is dimmed or not available, even with all of the perquisites are met.


Download it and manually install it.


Expand "Install Instruction" on the page - the Upgrade Advisor is close to the bottom, download it and install it.

Please note that after installation, there will be a separate menu under the Microsoft SQL Server 2012 folder for the SQL Server 2012 Upgrade Advisor. The "Install Upgrade Advisor" on Microsoft SQL Server 2012| Configuration Tools | SQL Server Installation Center or (x64) | Planning | Install Upgrade Advisor is still not disabled.
