Hello and welcome to Bleepingcomputer.
Here is the Corel web site support page link.
Which version do you have, the Pro or standard version?
Check this link for the standard and pro tabs.
Here is the Windows 7 compatibility link.
Try going to the folder Win DVD is installed in and try clicking the icon there to open the program.
You may need to run it under Administrator rights, which is possible by right clicking the icon and choosing 'run as administrator'
If the program runs Okay after this, you can right click the desktop shortcut icon and choose PROPERTIES, SHORTCUT TAB, look for ADVANCED then look for a box next to RUN AS ADMINISTRATOR. Put a check mark here, than OKAY.
You can also do this through the icon found in the folder Win DVD is installed in, however, this icon will not be a shortcut icon like I described above.
Hope this helps.
