With the CorelCAD May 2012 update we have announced the availability of an update notification feature within the application. In order to make this feature fully work for you with future updates, please download a revised version of that CorelCAD update.
The revision is available for download on the Patches & Updates page of the Corel website and has replaced the "May 2012 update".
If you're not sure which version you have installed, here's where you can find that information:
If your version is anything lower than 12.4.056 you should download and install the revised update to benefit from an update notification within CorelCAD when the next update will be released in the future.There is no need to uninstall the previous version of the software - the revision will update/ replace any previous version of CorelCAD.
Mac users should also install this revised update for an enhanced PDF underlay functionality.
