Hi Richard,
Sorry my first effort did not help you solve your problem. Here is some more
information. It is up to the manufacturers of programs to write them so that
they'll appear in Default Programs. This is why certain programs, such as
Firefox, appear while others might not. There is no way for you to add
individual programs to Default Programs. However, if what you want to
accomplish is associate certain file types with certain programs, you can do
that manually:
1. Click Start.
2. Click Default Programs.
3. Click Associate a file type or protocol with a program.
4. Select a file type from the list, and then click Change program.
5. Select the program you want to use.
If the program isn't listed, click the Browse button to find it.
I hope this helps.
