[RTTY] MMTTY Question

[Paul Kern via RTTY]

I have a question about being able to have two installations of MMTTY on the same computer.  This is not for contesting as a SO2R setup.  I have Radio A using a Signalink for AFSK running MMTTY on Computer 1.  I want to have Radio B using a microHam USBIII interface for FSK and other modes also on Computer 1.  Just curious if I can install a second MMTTY maybe in a different directory.  Thanks for any insights....
