Rod:
Thanks for staying with me when i was ready to give up. Here's what the Solution Explorer looks like in my little test project:

Solution 'TestPDFProject'(1 project)
Solution Items
TestPDFProject
My Projecrt
Form1.vb

My code looks like this:

Try
MessageBox.Show("Operations Guide.pdf exists: " & System.IO.File.Exists("Operations Guide.pdf"))
System.Diagnostics.Process.Start("Operations Guide.pdf")
Catch nullreference As NullReferenceException
MsgBox(nullreference.ToString)
End Try

In my first test the reference to the PDF was shown in the top(Solution) section, in the second test it was added to the bottom test. It was not shown in both sections.

The results were the same in both tests, The message box indicate that the file did not exist . The program throws an error before it gets to "Catch".

Thanks again, Rod for trying to help.

Ah ha! That shows the file isn't being installed where the program is.

(Can you go into the directory where the program is being installed and verify that manually? Otherwise it's still possible that the program has changed its default directory so isn't looking in the right place.)

If that's the case, then there's something wrong with the installation. I know you can handle that with an installation package project. I'm not sure how to do it with your current setup.

Finally GOT IT TO WORK after a lot of frustration. What I did was put the PDF form in a folder in the "ProgramData" file on the C drive, now I have to remember to be sure this is loaded when I make the setup program.

The code I used is:
System.Diagnostics.Process.Start("C:\ProgramData\M y Entertainment _ Collections\OperationGuide.pdf")
Me.StartPosition = FormStartPosition.CenterScreen

I sincerely thank you for the time and effort you spent trying to teach this old amateur programmer.... Makes me glad that I bought your book.

Sincerely,
Milt

I'm glad you figured it out. Sorry it took so long!
