The SOM Process Designer was developed by the IMC, however, IMC doesn't appear to be in the business anymore, therefore it's impossible to answer those questions since no official website is found. The only thing you can do is to get in touch with the ones where the software still appears, which is HP Corporation. I've used some search queries on Google and found out that SOM Process Designer appears on the HP website.

If the software is still available, a technician should provide all the necessary details.
