Minion does not start - no message (Win 7)

[Callads]

Hi,

i have minion installed on my laptop with Windows 8, and it runs without problems.
Now i wanted to use it with my desktop PC. OS is Windows 7 64 bit.

When i try to start it, it just does not launch - no error messages, nothing.
The minion.exe appears in the processes tab at the task manager.

Things i tried allready:
- Redownloaded several times
- Installed in default location and other locations
- Uninstalled all java on my PC and reinstalled the latest Java 7 Update 67
- Uninstalled Visual C++ 2010, and reinstalled it with the Minion Installation
- Run as admin and all compability modes
- Tried to run through Minion-jfx.jar

Any tips, what could cause this, or what else i could try?
Thanks in advance for any help.

Edit: i tried to post the log and xml files. But it seems there is no .minion folder under C:/users/<name>/
