I have had trouble with the most recent version of the software on both Ubuntu and Debian linux. However, this link to the older version of the software works fine.

I got this link directly from West. My problem with the new version was that while it would install, it would hang whenever it tried to open a transcript.
The "new" version is 20mb. This one is less than 2mb, but it is fully functional.
I could not find guidance anywhere in the internet for this issue, so I hope that this post helps anyone that is having problems.
