If you are a Pralana Gold member, your license entitles you to maintain copies on two different computers and to get free updates of the model corresponding to your license. Member download buttons are shown below (invisible if you are not logged in as a Gold member).  If you need a copy of the Read_Computer_ID file, please scroll to the bottom of the page and you’ll see the download button.

As a member, you also have the ability to ask for help via the Pralana Retirement Calculator Forum. Just click the Nav button at the top of this page to access the Forum.
