Office Activation Issues

Ran across some issues activating office 2010 on a XP computer today that had a corrupt install of office 2003. First the CD drive was missing easy enough fix clear the filters and now we can run setup from the disk. Not so fast setup wouldn't run because of a corrupt install of office 2003. Tried the windows resource kit and fix-it to remove but no luck. Finally ended up having to manually remove and run windows installer cleanup now 2010 would start up the installer but would fail at the very end of the install and roll off with a generic error and no helpful code to look up. After looking at the error logs in %temp% I found a code of 1603. First couple post about 1603 link to permission errors and problems with WMI/WBEM. So I ran a permission fix and WMI/WBEM repair from my trust D7 by foolishit.com after verifying the was an issue. And now for the first time office 2010 is successfully installed but complaining out about licensing and closing office. The final solution to this saga was to use the ospp.vbs to install and activate the product key. Now the office is activated and running like a dream. What a way to end the day!
