So, I got my copy of Win 8.1 Enterprise via Tech Soup. I'm a consultant with a 501c3 and they provided me the 8.1. I got into the evaluation program and worked it, and now that 10 is released, I cannot activate it.
Why? What do I need to do? I get a number of different error codes, but often it's this one: Error code: 0x8007232B
