Windows 7 doesn't need a 3rd party application to do this. You click on the file (must end in .iso) and Windows should provide the necessary prompts. I'd uninstall that program and let Windows 7 take a shot at it. Make sure you have the correct media type in the burner for the download you have.
For the life of me, I cannot figure out how to do this.
I am running Windows XP Professional x64
I cannot burn an iso image of memtest86 using isorecorder or any other iso burning utility.
However, when I started the isorecorder it gave me an error to go to Services and start the service..so I did and started both Imapi CD Burning and Imapi Helper but I just checked the CD burning selection was turned back off again.
Any help greatly appreciated.
Thanks,
Cheryl
