I have a Dell desktop at home with XP on it and WordPerfect.  I am currently using a desktop with Vista Professional running.  Is there anyway to move the WordPerfect program to the Vista computer?  Alternatively, if I upgrade the XP to Windows 7 will WordPerfect still be accessible?  Thanks!

You will need to manually install all your programs when migrating from Windows XP to Windows 7 which is fine if you have the installers.

You haven't stated your model of computer (we may be able to offer some advise with the upgrade to Windows 7). I have a multitude of unofficial driver sets for instance.

You haven't stated your version of Word Perfect. X5 for example is compatible with Windows 7:

X6 and X7 are Windows 8 compatible:

P.S. post on the Corel WordPerfect Forum. Word Perfect is not Dell preinstalled software and users there will be more experienced on the compatibility of the product and licensing:
