If you are installing a CorelDraw X3 Graphics Suite on your system unit but when you try and run it, you get this message:
The UI Language registration list is invalid.
Do not worry.. ;)
Here is the solution.
Open the c:\Programs\Corel\CorelDRAW Graphis Suite setup files\CGS13 directory and look for the EN.msi file. Double click the file to install the language pack and then all is sweet.
