Hi Rui ,

Target Word Count plugin works fine on my Trados Studio 2022, build 17.0.6.14902 (multiple languages, multiple files).

Which Trados Studio version are you using?

Could you please post the full stack as shown here: https://multifarious.filkin.com/2022/12/09/community-helps-those-who-help-themselves

The specific error message "An item with the same key has already been added." normally occurs when multiple versions of the plugin have been installed.  Perhaps try removing the plugin from these locations, reinstall from the appstore making sure you have the latest one and try again:

%APPDATA%\Trados\Trados Studio\17\Plugins\Packages
%APPDATA%\Trados\Trados Studio\17\Plugins\Unpacked

%LOCALAPPDATA%\Trados\Trados Studio\17\Plugins\Packages

Hi Paul 

I did what you posted, and... it still doesn't work.:(

It's alright though, I created a package for review, and send it to my friend, let her did the Target Word Count. She uses Studio 2021, and the plugin works fine in the project of multiple language pairs. (Or maybe it works fine because I only include one language pair in the package? IDK.) Like I mentioned before, this plugin works fine on single language pair project in Studio 2022. Have no idea what's going on...

Anyway, thank you! 

 Rui 

Thank you.  I installed and test this plugin this morning.  I also don't get any errors running it on projects with multiple language pairs.

If you want to I'd be happy to look at your specific project?  Can you share it with me?

Dear Paul ,

I'm sorry I just seen your reply! have been busy lask week. And sorry I can't share that specific project to you because the NDA. Instead, I can share some more detail of this problem in description.  

This particular project is created in two langauge pairs. A: Japanese-English. B: Japanese-Chinese.

The source files are idml files, and we have Translation memory & Termbase for both langauge pairs. I have tried Target Word Count for multiple files in language pair B, and it works just fine. It seems like the problem only appears in Language pair A. 

One more thing is that I have edit the source & target segement of A in Studio editor view, may that's the reason caused error. 

I hope these infos helps. Thank you a loooooot!
