If you try to install RF software on your computer running Win XP and receive the 16 Subsystem error, download and install one of these two fixes. I spent hours trying to resolve this problem by following suggestions and tips from other posts on this forum and a lot of remedies at Microsoft with trying to reinstall autoexec and config.nt files. Also tried the installation fix located on this website.
I don't know how these fixes were generated but after running the first of the two(XP Fix.exe), the problem was resolved in a matter of seconds. Didn't have to try the second fix site. Here's the links and hope it works as well for you as for me.
