For those who have installed the 2021 version of MCP Express and have not otherwise heard, this is the final release Unisys will make for this product. In August, Einar Flaathe kindly posted on comp.sys.unisys the following information that he had received from Unisys MCP Express Support concerning the release:

You are correct in that the MCP Express 6.0 content is the same as what was delivered 2H2020. The one difference is the original MCP Express 6.0 expired July 31, 2021 whereas the current package will expire December 31, 2021.

This is the last planned deliverable for MCP Express.

We encourage those who would like to continue to use an MCP environment to consider purchasing MCP DevStudio Personal Edition, or another ClearPath MCP Software Series offering, which provides an upgradable, non-expiring, supported environment.

One clarification I should make is that by "non-expiring" Unisys means that it doesn't expire on a given date each year. You license the software for a specified term, typically three or five years, and it becomes inoperable after that time unless you renew the license.

Presently, my understanding is that in the U.S. the cost of a Personal Edition license is on the order of $1500-$2000 USD per year, including maintenance and subscription.

  • Maintenance allows you to access the non-public portions of the Unisys support site, to download and install updates and fixes for your current release, and to submit trouble reports and new-feature suggestions.
  • Subscription allows you to upgrade major releases, e.g., from MCP 20 to MCP 21, during the term of your license. Subscription requires that you also purchase maintenance.

If you do purchase a license, I strongly encourage you also to purchase at least maintenance; otherwise you will not be able to receive any updates or fixes.

This blog to date has been mostly about installing and configuring MCP Express, as that is the topic on which we received the most questions. The bulk of what I have written, however, applies equally well to DevStudio editions and other MCP products. There is plenty more to say about MCP systems, so there are no plans for the demise of this blog.
