Did you ever want to know what all those settings do, but get an error when opening the help files?
Theres a reason for that. Microsoft decided that from XP onwards these types of help files were not secure enough. So the help included in many programs, inc R-Net will not work. They will fail in Vista, and in 7, 8 8.1 etc. Theres a fix. At least this fixes the 64 bit version of these newer operating systems. But thats what most are using today.
You need to take the help file program from a windows XP 64 bit (it lives in the windows directory, and is called winhlp32.exe even though its actually a 64 bit version - dont ask me why). And replace the one already in newer versions of windows. The one in newer versions is actually fake, it just sends you to a website explaining that it is no longer supported.
So take the file inside this .zip below, and replace the one you already have in your windows folder. Thats it, then help will work in the r-net and every other program. But its not that simple! Its locked and will not allow you to delete or overwrite it. But I did that from a boot disk. You can also do it from say, the rescue disk on most backup programs. Or sergeis USB boot tools. Etc. Or you can "unlock" it in windows and delete it.
This is the one you want. And its safe!
