Sorry for the dumb question..
I have been using JR for years but for the life of me I have never been able to find the command line launcher. I have searched the forums, FAQs, etc. but every result I have found seems to assume you know this already.
I have read that it is just MC<version>.exe in the program folder but all that happens when I click it is JRiver starts to re-install itself!
Some help much appreciated.
