Hi Jennifer Sunde

First, the obvious question... do you have SDL MultiTerm 2021 installed? If not, go to your SDL Account and download and install it. This should be all you need to do.

If you do have SDL MultiTerm 2021 installed or if installing it doesn't solve your problem, the next logical step is to perform a Windows Repair of SDL Trados Studio and MultiTerm.
This will repair links between the two pieces of software by checking for and replacing anything that is missing from their setup, for example.

Here is how:

1. Close all SDL applications.
2. Open the Control Panel:
   • Windows Vista/7: Start > Control Panel > Programs > Programs and Features.
   • Windows 8: Right-click on the screen at bottom-left corner and choose Control Panel > Uninstall a Program.
   • Windows 10: Right-click on Start > Control Panel > Select View by: Small Icons > Programs and Features
   • - or type 'Control Panel' in the search line on your bottom Windows toolbar.
3. Click/highlight the relevant SDL product from the list (e.g. SDL Trados Studio 2021 etc) and click 'Uninstall/Change' either on the top toolbar or on the right-click dropdown menu, then select > Yes > Repair. Allow it to run. This will take longer for Studio than for the 3 main components of MultiTerm. Do not repair either of the 'Remove suite of products' entries. These are only for uninstalling.
4. Restart Studio/MultiTerm.

All the best,
