No main class error error

[Garnet]

Greetings, after reinstalling win 7 (x64) keep getting error 'No main class' with clickable Ok button, and after clicking it, i have one more window with 'Failed to launch JVM" . Screenshots 1, 2 attached.
Getting this problem only with minion (Nero and other Java based staff, even minecraft is going well, without surprises).
- Tried reinstalling minion (3 different versions) like this http://cdn.mmoui.com/minion/Minion2.0.9a-beta.exe
- Tried reinstalling java ( online and offline versions)
- Tried to praise the sun
- No result
- Minion.log and Minion.xml not created.
