CorelCAD install error.

I have been attempting to install CorelCAD on my computer. I have a Dell Dimension 9200C with 4mb of RAM and am running Windows 7 SP1 with dual monitors. My Windows Installer version is 5.0.7601.17514.

The program installs almost to the end, to the point where the desktop icon is in place. When the install window reads registering software, it stops and I get the following message: " There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor." At that point the program rolls back the installation.

I've run Microsoft Fix It for uninstall/install with no success. I've tried to register the software first before installation but I receive an error message that the serial number is incorrect or is a legacy program without support.

I can't find anything on the Corel website or the Microsoft website that addresses my problem.

Any suggestions?

sorry I can not help your problem.
