Upgrading to Windows 7 64bit problems

Hello.
I am having problems upgrading my pc to the 64 bit version of windows 7.Whenever I put in the 64 bit cd an error message pops up saying that:

"the installation disc isnt compatible with your version of windows.To upgrade you need the correct installation disc"

I have run the windows 7 upgrade advisor and says that my computer can run the 64 bit version.
I am just curious as to wether its the cd that needs replacing or that my pc needs an update or something.
It also might be worth noting that even when the cd is in the drive and i reboot the pc,it doesnt auto run like all other os install cd`s, so i cant even manually install it like it recommends in the error message.

I have upgraded from windows xp sp2 to windows 7 32 bit for now, which was fine.

Any help would be much appreciated.
If necessary i can post a list of my pc`s hardware/software if anyone needs it.

 

You can't upgrade from 32 bit windows to 64 bit. It is a fresh install. The upgrade advisor just says you can "upgrade" to 64 by wipe and reload only.

 

Thanks you 2 but that isnt the problem im facing.
When i try to run the 64 bit cd, it comes up with a error window saying

"This installation disc isnt compatiblewith your version of windows.To upgrade, you need the correct installation disc.For more information,check your computers system information.To install a new copy of windows,restart(boot) your computer using the installation disc,and then select custom(advanced)"

that is word for word what the message says.
the thing is is that is all it does. there is no manual boot install and no window that opens to let me manually install.that is why i was wandering if its the cd or my pc that has the problem.

 

Did you change the boot sequence to boot first from your DVD in the BIOS? Then you would normally get a screen asking you where you want to install it or an option to wipe your hard drive clean to prepare for X64 installation. If it's a retail W7 then you should be OK to go, if it's an Upgrade disc you'll have to install it twice, once without the key and a second time with the key entered and then activate it.

 

It sounds to me like you have a 64 bit upgrade disk, as opposed to a installation disk, which is what you would need. :wave

 

Well, I guess MS finally just closed that loophole that has existed since Vista. If this is the case then Space_Rocks is out of the cost of an upgrade disc. Here's a recent article from Windows Secrets with a how-to.

I hope I'm not contravening MG's ToS.

 

Thank you all for the replies.
its done now...it was the bios not running the disc drive first.i changed it and it ran upon boot

thanks again people
:wave

 

Ya, I've got a full W7 Ult retail and will not buy an upgrade disk for obvious reasons. Well, Space_rocks only has this route to go. I really do wish that these things were marked clearly on the disk or at least the salespeople know what to ask. *sigh*
