I've just downloaded the latest version of Community Advanced Display Filter for Studio 2019.
First, I could not open an existing file for translation. The "Key already exists" error message appeared. Then, I uninstalled the plugin, looked for duplicates (no duplicates existed), restarted my computer and installed CADF again.
Now I cannot even start Studio, and the error message "Key already exists. Parameter name: Key" appears.
Where can I download any previous version of CADF?
I'm pretty sure you have not removed the duplicate plugin as instructed with the updated version. To avoid all doubt please clear them all and then reinstall just the ones you need.
Update: I found CADF plugin under C:\Users\User\AppData\Roaming\SDL\SDL Trados Studio\15\Plugins\Unpacked\Advanced Display Filter.
I deleted this folder but the folder with its contents is recreated upon starting Studio, and CADF is still there in studio.
ok - send me an email and we can look at this together on your computer over skype. email@example.com
Will be useful to find a problem that we are not aware of yet.
