Can't install Office 2007 in W7 64

[LJS]

My installation crashes half way through. I get an "unknown error" message and have to close the installer. Any suggestions for a work around?

What are you installing it from? If a download, re-dowload and try again, of from disks, try them on a different computer see if they work OK there. Check for any damage to the disks.
