I have installed K2 several times (and followed the uninstall pdf to make sure I had a clean slate to start with), I verified all my service accounts were set up with the proper permissions.  Everything is installed on one VPC for my own dev environment.  Yet I can't seem to get the workspace up and running.  Attached is a screenshot of the config error.

 Any ideas on what I can try, or look into?

 Thanks!

I would suggest opening a helpdesk ticket.  But here are a few ideas:

It sounds like this assembly in the gac is corrupted.  If you have another intstall of the same software version, you could try copying the assembly from that one and installing it in the gac on this install.  If not, when you uninstall, make sure this assembly is gone from the gac.  You might also want to download a fresh copy of the install files to make sure they are not bad.

Although I have not seen it myself, I have heard of cases where something goes wrong with the whole gac.  In that case, you might try un-installing and re-installing the .NET framework.
