Please can anyone show me how to code a macro in Excel to launch a pdf file. As it will be installed on lots of PC's I do not want to have to specify the path to adobe exe file, just the pdf (which I will know the path to).

I have tried
Code:
Task_Manual = ShellExecute(Me.hwnd, vbNullString, ActiveWorkbook.Path & "\CT38 - SHS Joint Software Manual.pdf", vbNullString, "C:\", SW_SHOWNORMAL)

but get 'Invalid use of Me keyword' error message.

I am still learning VB so an example of code would be most helpful.

Many thanks
