I'm not sure what to say about this.  It looks like the wrong window altogether.  I just tried it I get this:

The correct window.

I think if you can reproduce this all the time that a reset is in order and "maybe" it will help as it often cures odd behaviour.

Rename this folder (just add _old to the end or something, it's not important what you rename it to) and restart Studio:

c:\Users\[USERNAME]\AppData\Roaming\Trados\Trados Studio\Studio17

So the path would become this:

c:\Users\[USERNAME]\AppData\Roaming\Trados\Trados Studio\Studio17_ol

Hi Paul,

I tried what you suggested and more, I deleted every directory related to Trados in appdata, I deleted every reference to Trados in regedit, then I reinstalled Trados

the issue remains the same, the wrong window opens

there is something wrong with the registration of the .resource file

after a fully clean reinstallation the .resource file is associated with nothing

when I double click I get this message

Then I tried to associate the .resource extension with Trados

I double click, Trados opens, however the resource template this time is not displayed

At last I created a new resource template with the same name, then I replaced it with the existing one in the windows file manager, and now it looks like I finally can use it

It seems I am having exactly the same problem now:

When attempting to open a Language resource template, a window to open the TM pops up. Have you been able to resolve this?

Thank you!
