CDM+ includes a robust web update utility. We recommend that you check for program updates at least once a week and install any that are available. To check for an update, select Updateunder the File menu or click on the update icon in the toolbar. See the section Automatically Checking for Updates below for instructions on setting up CDM+ to check for updates from the Web at log in.

Access to a live Internet connection is needed to update from the Web. The process is generally very quick and ensures that you have the latest version of CDM+. When updating from the Web, no personal information is transferred, only your current version number that is used to determine which, if any, updates are available.

If you unable to download an update, an update CD may be ordered from CDM+ Support for a fee. Call 800-633-9581 to order.


Choose Update from the File Menu or click the Update icon 


A status window reading “Checking for updates” will appear if any updates are available. Otherwise a “No updates are available.” message will appear.

If there are updates available, the Update window will open, listing all updates that will be installed.

Every listed update will be installed—you do not need to run the update utility again for each listed update. However, some updates require a certain version before they can be installed—double-check the update notes to see if you need to re-run the update utility after installing available updates.

Click on an update to see the release notes. To download the update, click Install. A progress bar will appear next to the status, which will update to show the download process.

If you are working on a network and other users are accessing CDM+, you will see a list of users currently logged into the program appear. Each user must quit CDM+ before the updates can be installed. 

Once the update is complete, the program will restart, and all users may log back into CDM+.

A Note Regarding Version Numbers (click to expand)

CDM+ uses a standard version numbering scheme comprised of a major version, minor version, incremental version and release number.

The major version is the number beginning the version number, such as 9 in version 9.0r1. A change in major version represents the most significant changes from one version to the next. In many cases, a new major version represents a large number of new features or completely re-written and enhanced existing features.The minor version may change whan a signficant number of features are changes. In the version 9.0r1, the minor version is 0. This would change by going to 9.1r1, in which case the minor version becomes 1.

The incremental version represents the addition of a handful of new features. Going from 9.0.1r32 to 9.0.2r1 is an increase in incremental version.

Version numbers also carry a release number. This number follows an “r” in the version number, so for version 9.1.2r1, the release number is 1. During development of new versions, the “r” may be replaced with an “a” or “b” to represent alpha or beta releases.

Release numbers may have incremental updates, such as 9.0.1r1.1. This release is essentially identical to 9.0.1r1, but may fix minor bugs. Note that an incremental release is not the same as an incremental version. Incremental releases generally do not trigger an update message if you have have your CDM+ User Preferences to check for updates at startup.

Automatically Checking for Updates

You can set CDM+ to automatically check the Web for updates when you log into the program. This option requires that you have a live Internet connection. To enable this option, open the Preferences (see the section below on Preferences for more information on how to do this), select CDM+ User, select the General tab, then click the Web Update icon and check the option to “Check for program updates at startup.”

Manually Updating

If you are unable to use the update utility in CDM+, you may also install program updates manually from a downloaded installer file or update CD. It is strongly recommended that you backup your datafile before installing any update. See the Backup section below for more information on how to do this.

To update from a downloaded installer or installer on a CD, first locate the CDM+ Installer application:



Launch the CDM+ Installer and follow the on-screen instructions for installing the update. Once the installation has finished, quit the installer and open CDM+. A window will appear indicating that your version is more current than that on your server and that the server is being updated. If there are other users currently logged into CDM+, they will need to quit the program before you can continue logging in.

Once this process is complete, the update has been installed, and you may continue using CDM+ in a normal fashion.

Some updates will require you to install them manually on each computer. Double-check the notes included with the update to see if you need to perform an installation on each computer.

If there are users who were not logged in at the time of the update, they may see an message appear when next launching CDM+ that the most current version is being installed on their computer. This is normal and helps ensure that everyone on your network always has an up-to-date version of CDM+.

Using a Proxy Server with Web Update

If your network requires a proxy server to access HTTP servers over the Internet, you can specify a proxy server for the Web Update to use by going to Preferences, then to CDM+ System, then selecting the General tab and clicking on the  Web Update icon. Contact your network administrator for proxy server and port information.
