Getting an error when installing the RKS Fax program

Question

I purchased RKS program several years ago. I also purchased a Zoom 56k USB modem series 1063. I've re-installed RKS Fax program and now get an error message:

THIS IS AN UNSUPPORTED VERSION OF WINDOWS, PRINTER WILL NOT BE INSTALLED.

RKS (version 1.50) was running on my Windows 7 64 bit & my new modem works with Windows Fax & Scan program. I like using RKS FAX, not Windows Fax.

Answer 1

According to information found on the Internet, the RKS Fax application is compatible with Windows XP and Windows Vista. There isn't anything related to 64bit support. I have checked it, but even the official website is discontinued. The only thing you can do is to re-install the software again. This time, make sure to choose Run as Administrator when install the program and each time you launch it. Also, right click the setup package and apply a compatibility tweak. Go to Properties > Compatibility and choose a Windows version close to the latest supported one (in this case Windows 7).
