Windows Installer-Error opening log file-Verify location exists and is writable (for MS Office)

This concerns a DELL desktop, Dimension E510, with Windows XP Media Center Edition 2005, and Windows Installer Version 3.1. Attempted installation of MS Office Student and Teacher Edition 2003. Attempt unsuccessful! Getting the message:

"Windows Installer, Error opening Installation log file. Verify that the specified log file location exists and is writable."

Maybe something about the registry, ‘drive:\Windows\System32\msiexec.exe /V’, needs to be edited. Please help me install MS Office.
