Unfortunately no, nothing else is running and this is being run under an administrator account. I also tried the most recent offline installer with the same result.
I did run Process Monitor and captured the event. I was hunting for “ACCESS DENIED” errors in the log and found the following matching items, which does lead me to think it is some kind of strange permission issue:
“9:55:41.5671076 PM”,“avast_free_antivirus_setup_offline (1).exe”,“16532”,“CreateFile”,"C:",“ACCESS DENIED”,“Desired Access: Read Data/List Directory, Synchronize, Disposition: Create, Options: Directory, Synchronous IO Non-Alert, Open Reparse Point, Attributes: N, ShareMode: Read, Write, AllocationSize: 0”
