Hi Jeff,
Yes I am on a managed network.
I have completely uninstalled all Adobe software and run the CC cleaner tool. I am just waiting on the correct version (Win 7 64 bit Enterprise) of the creative Cloud desktop app from my administrator.
Unfortunately the page you sent me to didn't cover the error message I received. Please see my original post. I had no issues with Photoshop, Indesign, Acrobat; just Illustrator.
Cheers,
Steve
