When I run Wise Registry Cleaner a few issues were resolved but 3 remained unresolved.
Then McAfee also resolved a few issues and 5 remain unresolved.
Avast resolved every issue that remained and reported 100% fixed.
Then I could remove all the files in both desktop and program files that access was denied.
The solution for me was to run multiple anti virus programs, each program resolves only certain issues.
Thanks....again....again.
Please do install Arduino on your pc's!
