Unable to write to Exception

The wife and I are both getting the following error:

Unable to write to Exception: Cannot open file - C:/Games/Sony/EQ II Retry/EverQuest2.exe (13) - http://eq2.patch.daybreakgames.com/patch/sha/eq2/eq2.sha.zs/47/573/dae4248ba72d6fa28102558fe158f3ecf73. The file may be in use or you may lack the necessary permissions to install.

Rebooting tends to fix the issue but there that shouldn't be required. I am running as an administrator on Windows 10.
Anyone got any thoughts?

Did this happen before or are you trying to log in during the current downtime?

I have had it occasionally but for her it is almost every time there is a patch, even long after the system comes back up.

i'm getting same error.....even running as asdmin with virus scanner off

try rebooting byour computers........... worked for me

Sounds as if you're either crashing out of the game or your system is not tidying up properly when you exit. You can find the stray processes in Task Manager and kill them yourself if you want to avoid doing a full reboot.
