2. Go to the following folder:
   •  Trados Studio 2011:
     • Windows XP: C:\Documents and Settings\%USERNAME%\Application Data\SDL\SDL Trados Studio\10.0.0.0
     • Windows Vista/7/8: C:\Users\%USERNAME%]\AppData\Roaming\SDL\SDL Trados Studio\10.0.0.0
   •  Trados Studio 2014:
     • Windows XP: C:\Documents and Settings\%USERNAME%\Application Data\SDL\SDL Trados Studio\11.0.0.0
     • Windows Vista/7/10: C:\Users\%USERNAME%\AppData\Roaming\SDL\SDL Trados Studio\11.0.0.0
   •  Trados Studio 2015 / 2015 SR3:
     • Windows 7/10: C:\Users\%USERNAME%\AppData\Roaming\SDL\SDL Trados Studio\12.0.0.0
   •  Trados Studio 2017 / 2017 SR1:
     • Windows 7/10: C:\Users\%USERNAME%\AppData\Roaming\SDL\SDL Trados Studio\14.0.0.0
   •  Trados Studio 2019 / 2019 SR1:
     • Windows 7/10: C:\Users\%USERNAME%]\AppData\Roaming\SDL\SDL Trados Studio\15.0.0.0
   • Trados Studio 2021:
   • Windows 7/10: C:\Users\%USERNAME%]\AppData\Roaming\SDL\SDL Trados Studio\Studio 16
   NOTE: If you do not find this folder, make sure that these files are not hidden. See KB article Showing hidden files, folders and extensions on Windows operating systems
3. Rename the following XML files (for example, add an underscore before/after the file name):
   • BaseSettings.xml
   • Plugincache.xml
   • UserSettings.xml
4. Start again  Trados Studio (if possible with Administrator rights)
