Open Notepad with Shell command

The following works fine in my uncompiled program. But after compiling I get an error message that the About.txt can't be found. Is there a way of specifying the path:app with or without Shell to open the notepad file?

Code:

---

Shell "Notepad About.txt", 1

VB Code:

Shell "Notepad " & App.Path & "\about.txt", vbNormalFocus
