Network the two computers. Set open access for sharing between the two.

In "My Network places" on the lap top browse through the programs on your other computer, if there is a set up.exe file there just copy it over. If not, you may be able to copy and paste the entire folder from the program files window but that doesn't always work... Once you copy it from within My network places, paste it into your program files folder and see if it will work...

If you have a USB flash drive that's probably easier for the copy and paste option.
