If you have a software CD but have lost the product key is there anyway of finding the number or loading the software program without the key?

If you don't have the serial key and you haven't installed the program (or can't), then follow the software manufacturers process from their website on how to get a new key. If you legally bought the software they should give you a new key.

However, if you DO have the software already installed on some computer but just lost or forgot the key, then you can find the key by using Everest. Download a trial of Everest Ultimate from lavalys.com. Open the program and go to Software --> Licenses and it will list the serial codes for all software you have installed on your computer.

You might try downloading Belarc Advisor from download.com, tucows, program files,etc. It's a pretty good program and it just might give you your answer.
