Windows 7: How can I make a .iso of Windows 7 Professional

I recently purchased and downloaded the Windows 7 Professional 64bit upgrade, however I am currently running a 32bit version of Vista Home Premium.

I understand (from reading other threads) that it isn't possible to run a custom install, or even update from 32bit to 64bit; without creating an .iso file.

Could anyone help me; I've read through various threads telling me to do all sorts of things, then type "oscdimg -bC:\Users\James\Desktop\expandedSetup\boot\etfsboot.com -h -u2 -m -lWIN_EN_DVD C:\Users\James\Desktop\expandedSetup\ C:\7.iso" into the command promt window.
(Before you suggest checking the file paths etc are correct, yes they are)

However none of this is helping me. Could anyone please either give me a way around having to make an .iso file, or how to actually make the bootable .iso file, which i can either write to a DVD or run straight away.

Thanks in advance for any suggestions or solutions.

hi James, and welcome to sevenforums,

you've downloaded the upgrade, what format did the download come as?

Hello James, and welcome to Seven Forums.

Sorry, but you can only do a clean install when going from 32-bit to 64-bit, or the other way around. You can do a clean install with a upgrade version of Windows 7 though.

Just extract the contents of the file to a spare drive/partition and run setup.exe from there... no real need for a DVD at all...

The download's came in three files, Windows 7-P-Retail-en-us-x64.exe (I know that is the one I am meant to run, but when I do so I get the error message; "We are unable to create or save new files in the folder in which this application was downloaded. Please check the folder properties to make sure that you have security permission on the folder to write files and that the folder is not read-only." (The folders are not read only). There are two other .box files; setup1 and setup2.

And @Brink I was intending on doing a clean install, from Vista Home Premium 32bit to 7 Professional 64bit, but as I said above, I get that error message when trying to extract the files, I can't get past that part.

try this link: Make bootable iso from student d/l

Try not using C:\7.iso, instead put it on the desktop. C:\Users\James\Desktop\7.iso

That is one of the threads I was referring to in my third paragraph, I've tried several of those Command's in my Command Prompt Window; none of them have worked, the furthest I've got is "A required privilege is not held by the client"

That is where the file/s were originally, I have moved them to different paths, but they are currently back to the desktop, however I still have the error message if I try to run the .exe file.

Edit: Sorry I misread what you had put, I realise you meant to try save the .iso file to the desktop.

please also notice that you must : "Rt click and run as admin on the .exe. "
