CMS was written on an older platform and is no longer being updated. We have been encouraging customers to move to our newer software (Simple Church) which is being updated as new technologies become available.
It is important to keep your current operating system up-to-date for many reasons including security. However, CMS cannot run on the most recent Windows 10 update.
If you must continue to use CMS while you plan for your conversion to another software platform, follow the Help File instructions accessed by the following link: CMS Networking and Installation - How to migrate CMS to a New Server or Computer to copy your program to a Windows 7 computer.
We recommend moving to the new CMS SimpleChurch Solution.
