Unfortunately it does not works.

Did you check the .iso checksums to ensure you got a complete .iso download?

Installing the tool doesn't require any info.

No idea what you are saying.

A screen capture would be helpful.

I have an Optiplex 780 and when I use the official tool to get the windows 7 pro oa.iso (I had installed Linux on it and wanted to change it back to windows 7 pro) it says that an image exists but not for my machine what do I do?

Borrow a Dell Windows 7 DVD.

Or try to upgrade for free to Windows 10. I don't know if that is still possible.
