I installed 3 copies of JRMC16 the last two days. One on my Windows 2008 R2 server, which had no versions installed previously. I got a question or a warning that the computer needed to restart. It's a terminal server, and runs a few huge raid arrays, so I think not. The two other machines is Windows 7 SP1. One of them had previous versions of MC installed, and the other had none. Both machines was rebooted without a question or warning.
I would like to know what have changed. Why does MC now HAVE to be restarted? I would also like to know why there is not more warnings or questions before such a thing is forced upon you.
