I'm having exactly the same problem (except the deactivation issue). I have tried repairing, uninstalling/re-installing and changing the name of the folder C:\Users\%USERNAME%\AppData\Roaming\Trados\SDL Trados Studio\. (Workaround 2)

But there I saw only folders with the name of an older version (Studio 16), not the version I had uninstalled an re-installed again (several times, with and without turning my pc off and on again between attempts). It used to be Studio 18, I installed TradosStudio2024_18.0.2.3255, and I did not change it back to Studio 16, so I do not know what happened there.

Can you please help? Thank you in advance!

Hi Berthe Bogers 

If you have the same issue of Trados not opening, please delete LanguageCloudMachineTranslation.bin" from C:\Users\%Username%\AppData\Roaming\Trados\Trados Studio\Studio18

Kind regards,

Hi Elisa,

I did not have C:\Users\%Username%\AppData\Roaming\Trados\Trados Studio\Studio18 when I wrote my previous post, but somehow it returned of its own accord. That also happened a few months ago and I still do not know why it changed from Studio 18 to Studio 16 and back again in that folder.

However, I deleted LanguageCloudMachineTranslation.bin and now Studio is workling fine again.

Thank you so much for your prompt response!

Berthe

I'm glad it's working again Berthe Bogers 

As for the path issue, that is rather odd. Could you please provide a screenshot if you have the time? 

Kind regards,

Mysteriously, the folders have returned to Studio 16 again, but when I wrote you yesterday, it was Studio 18. That folder was not quite correct either, though, because in it were a folder Studio 18 and a folder Studio 18_old, but I had not created that last one. And now it is back again to Studio 16 etc. 
Fortunately, Studio is still working. Here is the screenshot of how it is now:

Hi Berthe Bogers 

You are not in the correct path.You had Trados 2021 installed at some point, that is all.

For Trados 2024, the path is C:\Users\%Username%\AppData\Roaming\Trados\Trados Studio\Studio18 

Kind regards,

I see where I went wrong: SDL instead of Trados. Thank you for your help!
