Stupid is as stupid does

I don't learn well.  Or so it would seem.  So let me tell you what I did this time.

I am working on a project that requires me to install the CRM Online Email Router.  I really didn't think too much about uninstalling the router for on-premise CRM, which I did, and the CRM Online Router worked just like it was supposed to.

I also did not think very much about the fact that I was installing a CRM Online component on the same server where CRM on-premise was loaded.

This morning, I was going to continue work on a CRM on-premise project but when I fired up CRM, I get this:

Hmm. In my line of work, we call this, "Bad."

I was wrong about that too.  It wasn't just bad, it was really, really bad.

I assumed that I had inadvertently created a conflict between the on-premise vs. Online versions of one or more DLLs. Deciding that it should be a simple fix to just uninstall the CRM Online router and reinstall the on-premise version, that is what I did.

The uninstall operation worked, the reinstall didn't.

No problem, I thought.  I'll just do a repair on the CRM on-premise software and we'll be good.

Nope.  That didn't work either.

Since I wasn't really sure what was happening, and I really didn't care ( since this was a development box ), I just uninstalled and reinstalled CRM - connecting to the existing installation.

And the point of your story was what?

Don't mix components from CRM on-premise with CRM Online.  That's what virtual machines are for.
