Can not reinstall Corel Draw x6

Yesterday I could not open any CDR files. I sent one to a colleague and she opened it just fine and resaved it for me. I still couldn't open the one she then sent back to me.

So I tried the REPAIR option for Corel Draw and that did not help. Then I tried to uninstall and reinstall, but this did not work. I uninstalled Corel Draw x6 and when I try to reinstall I get a message that says, " A newer version of Corel Draw is already installed. If you want to install this older version, first uninstall the newer version".

I had Corel updated to x6.3. How do I reinstall Corel Draw in this case?

This is the 32bit version I have installed as the 64bit version will not run on my PC at all. Win 7 Home Premium SP1 (64-bit OS)

Thank you.
