When installing Microsoft SQL Server 2012 Upgrade Advisor, you get the following message and the installation stops:
Setup is missing prerequisits:
- Microsoft SQL Server 2012 Transact-SQL ScriptDom, which is not installed by Upgrade Advisor Setup. To Continue, install SQL Server 2012 Transact-SQL ScriptDom from below hyperlink and then run the Upgrade Advisor Setup operation again
However, when you go to the provided link, Microsoft SQL Server 2012 Transact-SQL ScriptDom is unavailable for download and there’s just a text file to download instead.
This is a bit of a gotcha because the link provided is actually correct… But the download button on the page isn’t what you need. Instead, scroll down to the Microsoft SQL Server 2012 Engine Feture Pack Components heading and download Microsoft SQL Server 2012 Transact-SQL ScriptDom from there instead.
