64 bit - Why won't a new 64-bit Windows 7 laptop start a setup.exe file?

I'm helping someone set up their new 64-bit Acer Aspire One Netbook and have set everything up perfectly except the HP OfficeJet 4500 Wireless printer. The problem is I can't get the setup.exe file to work:

• put install CD in, double-clicked on setup.exe, nothing happened


• copied CD contents to hard drive, double-clicked on setup.exe, nothing happened


• downloaded newest driver from HP website, double-clicked setup.exe, nothing happened


• did right-click, run as administrator, nothing happened


• (put CD in another computer (32-bit Windows XP), double-clicked on setup.exe, worked fine)


• (other setup.exe files work fine)

How can I get this setup.exe file to execute on this computer?

Answer

Download the appropriate W7 64bit driver from here, see it it will execute and install.
