Well just to report back in case anyone else has a problem with uninstalling/installing itunes.
I also got the error insufficient privileges c:\programData\Apple Computer\itunes\sc info
I uninstalled itunes and related apple programmes using "windows instal clean up". I restarted and then cleaned the registry using ccleaner.
I then entered "msconfig" in the command box, and on the general tab i selected "selective start up" and checked the boxes "Load system services, load start up items, use original boot configuration". I then restarted the machine.
On restart i went to c:\programData and on the folders Apple and Apple computer I "took ownership". This is a function on my right button drop down menu.
I then followed the suggestions here:
windows vista general Error message: insufficient privileges to modify this file

Then I reinstalled itunes switchless.
Now I know this info isn't filled with links and the correct terminology but i'm not an expert. But this itunes error was driving me mad. And doing the above solved the problem like a dream.
If you have more expertise and know what I did in particular in the above to solve the problem please reply so that others might benefit.
