Error writing $$MRU_TOOL_BAR$$.rui.dictionary

I’m having an issue when I close Rhinoceros, i keep getting this error message:

c:\Users…\AppData\Roaming\McNeel\Rhinoceros\6.0\UI\System$$MRU_TOOL_BAR$$.rui.dictionary

Exception: The process cannot access the file because it is being used by another process.

-Already reset the toolbar to default settings
-Rebuilt the %appdata% AppData\Roaming\McNeel\Rhinoceros\6.0\UI\System
-Updated Rhino to the latest app.
-Confirmed i have full rights to all of the folders within %appdata%

Any ideas? this seems to be a new issue and i haven’t been able to find a solution or a workaround.

Hey,

I also have this issue, do you or anyone else already know a fix for this?

Here is the notification I keep getting

=Error Writing XML File

Thank you!

Hi,
I have a similar issue with a slightly different error message. Happens when I close Rhino.
I have the latest version.

Any solution?

This happens to me when I close two Rhino instances in quick succession. Despite the fact that the first window has disappeared, the just-closed instance of Rhino is still writing the toolbar file, so it is temporarily locked. Normally you need to wait 5-10 seconds between closing instances.

Thanks for your reply Helvetosaur:

Based on my recollection, that indeed was the likely cause. My just discovered fix was to go to the mentioned directory and then delete the offending file, ($$MRU_Tool_Bar$$.rui.dictionary). I then restarted Rhino, and closed it. All was well. A clean …dictionary file was created.
