SQL server 2005 installation caveats

Error: SQL server has detected incompatible components from previous installation of visual studio, sql server 2005 or .net framework. Please remove any components like that and install again.

Solution: If you already installed .net framework 2.0 or 3.5, only uninstall .net framework 2.0 from control panel add/remove. Then install sql server 2005 again. This time Sql server will install a later version of .net framework 2.0 as its requirement and install normally.
