Adobe Photoshop CC missing files in application support folder

Photoshop CC was installed and working perfectly. In order to free up hard drive space, I uninstalled Photoshop CS4.

Now every time I open Photoshop CC (or Photoshop CS 5.1) a warning message appears saying: One or more files in the Adobe application Support folder necessary to run Photoshop are missing. Reinstall Photoshop.

Dispite the warning, I click OK and Photoshop CC opens and runs fine.

I do not want to reinstall any old versions of Photoshop. So how do I get rid of the warning message?

Thanks,

Peter
