I can't install the 3.5 version on Windows 7. Is there an update for this in order to install it on my OS? Also, is there a phone number to contact the developer?
The 3.5 version of the program was designed for an older version of Windows OS. You can try to update your program's version to the latest one. To obtain an upgrade, you can visit the official website. If you still have problems on running the newer version on your OS, you can use Windows XP Mode provided by Microsoft. This will help you run older programs on Windows 7.
You can contact the developer using the phone number available on the contact page.
