Unable to uninstall

Im having issues with uninstalling old versions of photoshop, lightroom and acrobat. They're taking up space on my computer. 

I downloaded them in a free trial and then tried to uninstall, eventally getting rid of creative cloud launcher. Now every time I try to uninstall I get a pop up  "Specified product is not installed on this machine. Please quit installer and start over"

I now have creative cloud again through uni but I don't have the option to uninstall older versions so its still taking up space.

Any help would be very appreciated

Thanks
