When I tried installing SQL Server 2008 Express, the install failed due to this line. How can I circumvent this, or fix the issue?
For the features you've selected (not shown), you'll need to uninstall the 2005 tools before you can proceed.
Attempting to circumvent this by some means will probably result in a corrupt installation -- why did the SQL team add a rule check specifically for this case? Best to not mess around with it...
Note that the text in the Status column is clickable, and it will tell you more specific information for each rule check.
