Try to start the Minion.exe file with admin privileges. And update your antivirus tools to allow access to the Minion install directory, to c:\users\<your windows username>\AppData\local\Minion (check if the folder exists, even if Minion was installed to another folder -> this is the deault minion install folder).
This is alo mentioned at the Minion troubleshooting guide so please follow the hints provided there:

If I do not create an exclusion in my antivirus Minion.exe will be blocked and even the start + updates will make my PC hang and be troubled.
With the exclusion added it will start, show the update dialog, and update fine + show the game selection screen afterwards.
