trouble with uprading from win7 32 to win7 64

Well im trying upgrade from win7 32 bit to win7 64 bit on my computer, but I get the error when I use the setup.exe "The version of this file is not compatible with the version of Windows you're running.Check your computer's system infomation to see whether you need an x86 (32-bit) or x64 (64-bit) version of the program, and then contact the software publisher." . I also try to boot from disk , but it get stuck at the window screen with just my mouse pointer showing . Any help would be great - Thanks

well I cant even get to the custom or clean install option , after i boot from disk .. windows files are loaded then im stuck @ a blue screen with only my mouse pointer . Any help would be greatfull -thanks

And my Bios are already set to boot from cd/dvd (well it gives me the option to boot from cd)

Not sure what it can be - thanks for all the help so far Ricc46

Wait longer for the installer files to load after booting the DVD.

hi change the boot priority the disc drive instead of the harddrive first then try runnin the disc from bios
