Some antivirus programs require entire folders to be selected instead of a single file.When this is the case, the file paths below are what you should use. If required by the anti-virus program, include all subfolders since every file is critical to run the game.
OK this is getting out of hand now. After I managed to get this to work by running a repair (it happened more than once, that's why I'm back at this post now and not earlier), this time repair won't work and the game still can't start. I tried to delete the Program Data folder but still it won't start. After the repair is completed I'm getting the following error:
"Error 1005 - OSError_AccessDenied. Access denied. A file cound not be updated due to either insufficient permissions, or the file is in use by another process."
This is getting really frustrating because it happens at random times and for no particular reason. It happened at least 3 times after this post was created.
Edit: I also tried creating an antivirus exception for ESO but again same issue.
Edit 2: I tried to run the client as an Administrator but yet again, nothing happened.
Update: I managed to solve this by deactivating my firewall during repair and it worked. Please address this issue because it seems to occur everytime a new patch is available.
