When I run the installer, it says "This will install Minion. Do you wish to continue?" When I click "Yes" the Setup Wizard window come up saying "Press Next to continue" and then closes immediately.
I've tried disabling my anti-virus and setting the installer to run as administrator, neither of which resolved the issue.
It seems as though my anti-virus likes to keep quarantining things even when it's disabled. I tinkered with the settings and set it so that instead of automatically quarantining threats to show an alert instead. When the alert popped up, I told my anti-virus (COMODO) to report it as a false positive. (I'm assuming, of course, that your software doesn't actually have a virus in it)
