Hello Andrea Mason ,

Have you checked the plugin folder?

You should find this as follows -

C:\Users\swhale\your name\AppData\Roaming\SDL\SDL Trados Studio\15\Plugins\Packages

If yo cannot find this folder- ensure hidden folder is visible

You can also go to your downloads folder and copy the plug into the relevant folder- then you should be able to double click and install the plugin.

Dont forget to close Studio before installing the plugin and then restart after installing.

Hi Steven

I had already tried your solution. That's what I meant when I said I'd added the downloaded files to Packages manually. Double clicking didn't start the manager.

I did eventually get it to work. One of the things I did was to rename the Studio 15 folder, then change the name back. I also reinstalled Studio with administrator rights (which is what I had done in the first place).

I have no idea how I got it to work. It took me 5 hours.
