Installing 64bit Windows7 on my 32bit Vista

[Azryel]

I am trying to install a 64bit Windows 7 on my 32bit Vista computer... I have run the upgrade advisor thing and it said that it should all work...
I bought a Family Pack with 3 upgrades and it has both a disc marked "32-bit software" and one marked "64-bit software". I want to get the 64bit windows 7 home premium so I inserted the disk and tried to run the Setup.exe but I get an error saying

"The version of this file is not compatible with the version of Windows you're running. Check your computer's system information to see whether you need an x86 (32-bit) or x64 (64-bit) version of the program, and then contact the software publisher."

I then tried to run the file as administrator and then get a different error saying

E:\setup.exe is not a valid Win32 application.

What am I doing wrong here?
I have already installed 1 of my licences on another computer but then I installed a 32-bit Windows 7... I know I have to do a clean install to go from 32bit to 64bit but shouldn't the disc work on my 32bit system? :S

Hello Azryel, welcome to Seven Forums!



There is no upgrade path from 32-bit to 64-bit Windows, it will have to be a clean install; have a look at this tutorial at the link below and be sure to post back with any further questions you may have and to keep us informed.

Do a Clean Install with a Upgrade Windows 7 Version



If you have to upgrade because of data you don't want to lose on Vista you can use the 32-bit disk to do so.


Just to be clear, you have to boot the Windows DVD to do the install, it can't be run from within Windows, have a look at this tutorial at the link below.
