JoinFS It does not open W7

[RevuMac]

Hello everybody, my name is Revu.

Me and some virtual squadmates who use JoinFS.

But to a friend, with windows 7, after installing JoinFS, the program does not open. It does not give error.
It does not close (Because it does not open)

What can happen?
You have tried to turn it on with other window compatibility ... administrator mode ... but nothing.

Best regards, Revu.

Is antivirus software installed?
