Hello,
I'm also using Windows 10 and I can't open the PPF Transit file for translation in Trados.
I have downloaded the Transit Package Handler app and was able to open the project in Studio 2015. I can see the Transit file in the Projects/File folder. When I double click the file to open it for translation, it doesn't automatically take me to the Editor View. With a right click on the file in File folder the button Open for translation is grey and I have the message “No translatable target language files selected”.
Is there any solution for opening PPF file with Trados in this case?
