Win 10 Pro install fails, produces "...cannot access..." error message

I tried to install flywheel as admin in Windows 10 Pro and got an error message. I tried again after disabling SUPERAntispyware, Malwarebytes and Bitdefender Antivirus Plus 2018 to no avail. (I have to admit that I’m not 100% certain that all of Bitdefender features were disabled. Error message reads: “C:\Users\My Name\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\L…” which was followed by “windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item.”

What do I need to do to rectify this?
