I have platinum 32bit installed and It's working fine I also installed platinum 64 bit with problems and can only find platinum 32 bit in add or remove programs in control panel. I want to uninstall 64bit without interfering with 32bit. I don't see any way to uninstall the 64bit version how do I do it?

Generally if there is no uninstall option it indicates corruption in the system used to do the uninstall. As a first effort try installing the program again. That will generally replace bad files with the ones you need to run a standard uninstall. You can use Revo Uninstaller free to monitor the second installation to get a more accurate uninstall. Or if you cannot do the reinstall Revo can generally get rid of the installation pretty well. Manual cleanup has also been posted to this forum on multiple occasions.

I believe C3 installed programs do not appear in the Windows Program Control Panel. This is because C3 controls installation. Right-clicking the item in the C3 should have an uninstall option.
 

I'll defer to Scook on that. If CCC has its own uninstall, definitely use that.

Thanks so much for the help! I created a mess because I upgraded from Sonar 8 all the way through to Sonar Platinum and even though my O.S. is 64bit, I was running Sonar 32bit and have amassed a lot of plugin's.
I also created a lot of projects and still have X2, and X3 installed so there is a lot of shared plugin's and I have to clean that up and see what 32bit plugin's I have that are 64bit capable and when all that is done I'm going to do a clean uninstall and Install Platinum 64bit (only).
