Office 2003 installation on your computer is corrupted

Problem: Removing Office 2003 and installing 2010 produces error

Consequently, Office 2010 can't be installed.
Registry solved this problem;
run - cmd - regedit:
HKEY_CURRENT_USER\Software\Microsoft\Office
HKEY_LOCAL_MACHINE\Software\Microsoft\Office
To:
HKEY_CURRENT_USER\Software\Microsoft\xOffice
HKEY_LOCAL_MACHINE\Software\Microsoft\xOffice
