Please see the two attached images
I first Install SQL Server 2008. It installed successfully partially as database services, analysis service got failed. I then thought of Installing latest released R2. For that i had to uninstall previous installed SQL Server 2008. I uninstalled all of them except Microsoft SQL Server 2008 R2 Data-Tier Application Framework (not able to uninstall).
Now i am trying to install anyone of them.
When i open anyone of them i am getting "1st Error" (see attached image). I clicked continue and setup begins.
the setup begins and all valid are tests are passed. The 2nd error i am facing at setup support files.
I am concerned about both but most important about second one as i am not able to continue with my setup.
What i have done
a. Uninstall SQL 2008
b. Run Registry Cleaner
This happens with R2 version as well as without R2 version.
