Installer is corrupt
I am trying to install version 2.1.5 in Firefox 4.0. It downloads, and then won't install because it says the installer is corrupt.
The Word add-in v2.1 installs correctly.

The other fixes I tried were deleting the cache, deleting the extensions.ini etc. files, restarting Firefox, etc.
Either way it's now working fine. Hopefully it was just some problem very specific to my installation that. I'm sure if it's a problem for others you'll here about it soon enough. ;)
