Did you create that file yourself? How come it is there when you got the message it can’t be open for writing.? Something is seriously wrong with your system, like antivirus is playing games, or you did not run full setup in first place, file is read only or locked by another process. Get hands-on help from somebody who knows computers, because forum is not really good vehicle for solving individual computer issues.
The issue may have been because this was a back up computer that was previously a work computer. I completely wiped my hard drive to my sure there were no permissions or settings issues from work and reinstalled everything. It works now.
