HI, i purchased this off Microsoft under the Ultimate Steal thing, so it only cost me £40. It directed me to a link to download the 502mb exe file named ' X12-30307.exe ' . However my problem occurs when i click the exe to run the program. The first stage is windows shouts at me for permissions, then it starts to extract the files. It can range between ~ 20% and 80% before stopping and returning the error message '' The installation of this package has failed.'' I have run as administrator, run in various compatibility modes, re-downloaded the file 3 times, ran in safe mode, all to no avail. My only guess is that the 'master' copy of the file is corrupt and thus all downloaded copies of it, or something in windows 7 is stopping a file from beign extracted. Any help would be great. Notes: its 64-bit Windows 7 Professional, and i would create an ISO image, however i cant extract the files to do that. Its like a parcel with too much tape. Also trying to extract though DOS didn't work. And i have plenty of space left on my hard drive to install.
