I have to use Barracuda IM for one of my clients*.  I typically only sign in when we're shipping a new release though.  Today is one of those days, and I tried to install the client on my Vista machine, but I'm not having any luck.

Another Barracuda IM client is currently running. You must quit the running program to continue with the Barracuda IM client installation.

Needless to say, this machine has never seen Barracuda before, so the installer must be making some sort of a mistake.  My client is going to check to see if there's a 64-bit install.

* This is by NO means an endorsement of Barracuda IM.  I'm not a fan myself, but my client requires it.
