It's helpful if you tell which version of the software.  I'll assume 2021...

You may have to do a MultiTerm reset and it might help. Rename this folder (just add _old to the end or something, it's not important what you rename it to) and restart MultiTerm:

c:\Users\[USERNAME]\AppData\Roaming\SDL\SDL MultiTerm\MultiTerm16

If it's not 2021 change the 16 for 15 if it's 2019 for example.  You'll find the number when you try to navigate to this folder.

Hi.

Sorry, version is 2019. 
She already did this as it was part of the support guide which I mentioned. Maybe I'll need to take a remote control for her computer if the folder was correct one, I'll confirm this later. 

Ok,
Confirm, right folder was renamed.
After that, we renamed all SDL folders (AppData\Local\SDL and \Roaming\SDL)
No luck with this.
Then, we reinstalled all applications. Doesn't still work.

At the sametime, I installed this to other computer, works well in fresh installation / user.

Here's more info about the error:

Forget to mention earlier that it doesn't work with a new user aswell. So the issue is not with the user profile. Any ideas?
