Take a look at this and see if it helps
You mention this "I have tried running as administrator but have been unable to."
Do you have an Administrator account on the PC, as far as I remember you need to be able to right click either on the shortcut or the Photoshop.exe from program files and select Run as administrator
Thanks! I just tried that and unfortunately it still looped. Will try again after work with the Firewall off to see if that combo does it.
And regarding the article, I tried that yesterday forgot to mention that one.
Ran as administrator with firewall turned off, did not work. Tried an Adobe cleanup tool, did not work.
