Install visual sequencer on windows seven

Hello,
I try to install the visual sequencer on a laptop asus dual core with windows seven. The install work well, but when i try to use the program i get this error :
Error reading ComCombobox1->Comproprety : Registry error (whith error code 2).
Can anyone help me ?

I try to install in another pc hith windows seven and i get the same error message.

This typically happens if you do not have any serial ports on your machine when you start up the program. Try plugging in something like the USB to serial adapter that you will use to talk to the SSC-32 and see if that solves the problem.
