Ok, another product update question. Created an MSI application for MS
Office. Installed the application on a machine then downloaded and
slipstreamed a patch into the administrative install and then bumped the
GUID. Reinstallation starts, but then I end up with an error message: MSI
returned Error Code: 1638 (Product is already installed....) How do I get
around this?

Thanks for any help.
