SMSS will start for one user, but not another? We have a SQL Server 2012 and SMSS 2012 installed.  The C:\ recently ran out of space due to a misconfiguration, and now we have 1 user who cannot start SMSS they receive the error:

"Cannot find one or more components. Please reinstall application"


However when I login with my domain admin account, I can start SMSS perfectly fine.  We are both in the server Administrator group.  I have also "repaired" the SQL Server tools (which includes the SMSS app) on the box with no change in behavior.

Is there a log file somewhere I can check to see why SMSS will not start for this one user?
Perhaps something in their documents\user data profile got corrupted. If you've fixed the space issue, then I suggest running a repair on the application (or installing a newer version - you can manage SQL Server 2012 with SSMS 2014 or newer, and it's free - installation instructions in this answer). However it may still end up being hosed because of that user's profile - if so, as a next step, you could back up their files and re-create their profile (though I do concede that this will force you to lose a lot of their other settings etc).
