Problems: XP 32-bit to Win 7 64-bit Professional

  exdragon 11:37 AM 08 Jun 12

I'm still having problems with this: the 64-bit disc is being reported as the setup.exe not being a valid Win32 application. There was also another message saying the disc isn't compatible with the operating system. We've tried booting with the disc in and also booting up and then putting the disc in (following 2 different sets of instructions, one from the MS website and the other from the booklet which came with the disc).

The BIOS is ok, set to boot from the CD/DVD drives first. The 32-bit disc boots as you would expect.

Obviously doing something wrong, but can anyone help before murder happens in this household?

A damaged disk perhaps? you could download and burn an .ISO from here Win 7 .iso, with the added bonus that it already has SP1 slipstreamed into it saving time on updating after initial install.

Are these the instructions you are following? enter link description here

In that case I suggest you follow the advice of Chronus

Sorry - I don't understand. Why can't I just use the disc I've bought?

If it boots ok from the 32bit dvd then it must be prob with the 64bit disk, either it is scratched or dirty or something.

Microsoft's 'Custom option' is just to tell the pc to shut down and boot from the DVD.

So miss that step out and just boot from the W7 dvd.

Also you should only have one harddrive attached (to prevent problems), so disconnect any others and other equipment, printer etc. while you install W7.

Just wondering if your board supports running a 64-bit OS as the error shows not a valid Win 32 application?

You can't 'upgrade' 32 to 64 as such.

Further info, moving onto 'double install' method (if needed)

64 bit processor is of course essential, as mentioned.

All sorted and it's now working through 106 updates.

Believe it or not, once we disconnected the CD drive, it installed. Heaven knows what that had to do with it, but there you go!
