I downloaded the COMSOL 4.3a compact DVD image, double clicked it, then a "COMSOL 4.3a INSTALLER" interface showed.

When I clicked the "Change license" button, a window pop out that says "specify an existing COMSOL 4.3a folder". I used the default "C:\Program Files\COMSOL\COMSOL43a" and click open button. Then a massege that says "invalid destination folder. Wrong version of existing COMSOL 4.3a folder" showed up.

What's that means and how can I solve this problem? Thank you very much!
