Can't re-install or update Adobe Illustrator 2017 (Please see summary of error)

FATAL: Error (Code = 145) executing in command 'MoveDirectoryCommand' for package: 'AdobeIllustrator21-Core', version:21.0.2.242

FATAL: Error occurred in install of package (Name: AdobeIllustrator21-Core Version: 21.0.2.242). Error code: '145'

WARN: Target directory already exists: 'C:\Program Files\Adobe\Adobe Illustrator CC 2017\Support Files\Contents\Windows'

I just got this when trying to install the latest update of Illustrator. And I can't even delete the 'C:\Program Files\Adobe\Adobe Illustrator CC 2017\Support Files\Contents\Windows' folder as it is protected. I am trying to give myself administrator privileges to this folder but I'm completely locked out of it.

So then I tried to uninstall the program. It uninstalled using Windows > Control Panel > Add/Remove programs and I was able to delete the rest of the folders within 'C:\Program Files\Adobe\Adobe Illustrator CC 2017' but not 'C:\Program Files\Adobe\Adobe Illustrator CC 2017\Support Files\Contents\Windows'

I tried to re-install but I am getting the same error message I posted above.

Please advise. Thank you!

Thank you! I'll try that. One question though, do I have to uninstall all my installations and then re-install everything or just the CC desktop app (and not the full programs such as PS, LR, Premiere, After Effects etc...)

Thank you!
