I own Click'N Design 3D version 126.96.36.199 and have Windows 7. After loading, it does not work. Is this because of the Windows version?
Your version of Click'n Design 3D is lacking Windows 7 support. A newer version like 5.1.4 has native Windows 7 support. On the other hand, the software is not available as a standalone and now it's bundled with CD Stomper. Installing a newer version will fix your problem.
