I tried installing office 2003 on a new windows 7 64bit pro computer.
After much hacking, Outlook would still not come up. There were many error messages, but the most significant was that the application version was not correct.
Turns out the computer came preinstalled with office 2007 activation assistant which seems to treat office 2007 as partially installed (even though it does not appear in the installed programs list).
I used system restore to return to the point before this mess started. Now, what is the best way to completely remove office 2007 and start over? I found one web site that suggest i download trial verision of office 2007, install it, then uninstall, then uninstall the office activation assistant. I that sound advice?
