Some of the users I support use adobe 5.0 and others have adobe 4.0. I am trying to shell adobe to open a file through vb6 with the following code:

for adobe 5.0 users:
Shell "C:\Program Files\Adobe\Acrobat 5.0\Reader\AcroRd32.exe P:\archives\" & JobNo & "\Plan Rack\Archived Plans\PDF_Files\" & PDFName, vbNormalFocus

for adobe 4.0 users:
Shell "C:\Program Files\Adobe\Acrobat 4.0\Reader\AcroRd32.exe P:\archives\" & JobNo & "\Plan Rack\Archived Plans\PDF_Files\" & PDFName, vbNormalFocus

the adobe 5.0 users this works fine but for the adoe 4.0 users I get errors that say the document does not exist.

My variables JobNo and PDFName are correct and exist

I know I can just updgrade everyone to adobe 5.0 but some of my users are not allowing me to upgrade them.

Does anyone know what I could be doing wrong.

Thanks for your help
