Use this in all old versions of R:base
Zip command /c 'C:\ProgramFiles\Adobe\Acrobat 5.0\Reader\AcroRd32.exe|/p /h C:\Cust.pdf'
Some machines you might need to replace command with cmd.
I recall that the Launch version with 6.5 had problems with spaces in the
command line. After a bit of playing with it, here is what worked for me...
LAUNCH '"C:\Program Files\Adobe\Acrobat4\Acrobat\Acrobat.exe"|"/p /h
C:\Temp\IllJoe.Pdf"'
All the Quotes EXCEPT for the beginning and closing quote are Double.
You're Welcome!! ;-)
