I'm purchased Parallels 5 for the sole purpose of running ESRI's ArcGIS software. Unfortunately I cannot even load the latest trial version. I downloaded their trial package from here: http://www.esri.com/apps/Products/ArcGis/Eval10/ 3.7GB later I have a pretty disk image. When I try to open, it wants to burn the disk image to a DVD using the Windows Disc Image Burner. Unfortunately, Windows does not acknowledge the disk through this program instead giving me: "The write failed because the driver returned error information that could not be recovered from. (Error code: 0xC0AA0301)" I've also tried Nero as suggested on another thread. While it can see the disk image and knows the file type, it seems unwilling to copy it to an actual disk. Even though I can click on the disk image from within the Copy Disc tab, it does not bring it up as the source drive. Any advice on this?
