Hello Arthur,

What version of Studio?  I would hazard a guess that you should try a Studio reset but the command differs slightly between versions.  So try renaming the folders here:

   C:\Users\[User_Name]\AppData\Local\SDL: rename the SDL Trados Studio and ProjectApi folder

   C:\Users\[User_Name]\AppData\Roaming\SDL: rename the SDL Trados Studio folder

I'd have been more specific if you told us what version, but you can probably figure it out from this.  If it doesn't resolve your problem then please log a support case.  Go to the Knowledgebase;

Then go to the tab called Solution Finder  ( ) and now go here;

Download & Installation Problems

- I use SDL Trados Studio and/or SDL MultiTerm 2009, 2011, 2014 or 2015

-- The installation went fine but now I get an error message etc

--- The problem occurs in (pick the appropriate tool/s)

---- None of the articles resolved my problem (if they didn’t!)

Follow the route for your problem and if there is no answer that helps by the time you get to the end you'll be presented with a form to contact support.  Complete all the fields in the form making sure your email address is entered correctly or nobody will be able to get back in touch with you.

Also use the Chrome browser to log the case if you have it; you'll get more success in completing the form.

Paul
