SQL Server 2008 R2 Install

Now that it’s gone to RTM I’ve just updated my development server to SQL Server 2008 R2 and hit an error that is a little weird.

The install was blocked because it thought I had the SQL Server 2005 Express Tools installed.  However this is a machine that has never had anything other that SQL Server 2008 on it.

Searching around on the internet I found a post on the blog that covered why this is the case. 

Basically the problem is that SQL Prompt and SQL Search from RedGate add a registry key (at least the version of SQL Search that I had installed did) that fools the installer.  Simply uninstalling SQL Search and hitting “re-run” in the SQL Server 2008 R2 installer solved the problem and allowed the upgrade to be applied.
