I got it worked fine! Download W2000 drivers for mustek scanner 1200 CU, (probably all Mustek scanner will function with this workaround) Open regedit and edit key HKLMSoftwareMicrosoftWindows NTCurrentVersionProductName from Windows XP to Windows 2000. Install drivers, and before a restart edit key again to Windows XP. It worked for me! Not all photo editting software works with Xp so remember this!
