CMH Software FAQ's

  • Where are you located?

    Northwest Montana, Libby to be exact.

  • I bought a single version of your software. Can I install it on multiple computers?

    Basically the software is for one person. If you want to install it on your home and work computer we don't have a problem with that as long as its not being used by two people at the same time.

  • What are the differences in the Student and Full versions?

    There are only three differences in the student and full retail versions.

    1. Price - The student version costs much less than our retail versions do.

    2. Labelling - The student version in labelled in the software as a student version.

    3. Upgrade Options - The student version is not able to be upgraded.

  • How do I order a School or Student version?

    Easy, give us a call at 1-800-680-7638 or 1-406-293-4977.

  • Is a yearly fee required to use the software?

    For most of our software the answer is No, once you buy it no subscription or maintenance fees are required. If we come out with a new version you may at their option upgrade the software or continue using the old version.

    We do have a 1 year subscription option for our Constructor Student versions. These are for students only and not for installation at schools.

  • What is a Site License?

    A site license allows a school or training facility to install the software on unlimited computers at one physical site. This would include all locations at a college campus, but not multiple campuses in different towns. Please call us about multiple campus discounts.

  • Do you have training materials or books?

    We have electrical/electronic/hydraulic reference posters and cards.

    More Information

    No books, but we did a Constructor version for a book Frank Petruzella wrote for McGraw Hill. It's called "Electric Motors and Control Systems". It's popular in motor control classes across the US and Canada. The second edition of the book/software will come out in June 2016

  • Do you have your EULA online?

    We have the EULA for our software (Constructor and the Residential Wire Pro) available here.


  • Do you have a Mac version of the Constructor?

    Sorry, we don't have a Mac version available. The software is only for Windows 7,8 or 10.
    We don't support it, but some users are running Windows on their Macs (Parallels, Virtual Box and the like) and are running the Constructor.
