Try os.system("c:\\program files\\jasc software inc\\paint shop pro7\\psp.exe")
MORE LATE BREAKING NEWS:
Did you read the error message? I'll bet it said Cannot find the file
'c:\\program files\\jasc' (or one.... Notice that the first blank in the
path is seen as the end of the program. If you were entering this command
at at DOS prompt you'd need to put it in "" to have the OS take the entire
path name. So let's put it in quotes:
os.system('start "c:\\program files\\jasc software inc\\paint shop
pro7\\psp.exe"')
Which gives us a DOS window with c:\program files\jasc software inc\paint
shop pro7\\psp.exe in the title bar!
Look up start in help:
Starts a separate window to run a specified program or command.
start ["title"] [/dpath] [/i] [/min] [/max] [/separate| /shared]
[/low|/normal|/high|/realtime] [/wait] [/b] [filename] [parameters]
So the first quoted string is taken as the title. That leads to:
os.system('start "arbitrary title" "c:\\program files\\jasc software
inc\\paint shop pro7\\psp.exe"')
and Bob's your Uncle.
