Had the same problem. Here's my guesses as to why and how I fixed it (in Windows).
I've got a really old R1, so I've been using old software. I tried updating to the latest MC, and got the same error. I'm guessing the latest MC has an issue in creating the printer profile if there isn't one on your machine already.
I downloaded the 1.75 version, and it opened fine. I went through the "create an online account" and picked out the printer I have. Then once it gave me the basic desktop, I clicked on "upgrade available" at the top and walked through the steps to install the newest version.
Now the new version opens fine.
