Office 2003 SP3, error message that the expected version of the product was not found on my system

What is the cause?

This issue normally occurs:

- if you have language pack(s) installed for WSS / MOSS AND
- The language pack(s) do not have correct Service pack applied to them

How to resolve this error

STEP 1: Install the correct Service Pack for the language pack; then install the CU
STEP 2: Install the CU; then install the Service Pack for WSS/MOSS; after that install Service Pack for the Language Pack.
For example:

In the case of April 2009 CU, install the CU to the farm [Assumption here is the SharePoint farm is already installed with SP1+Language Pack SP1+some cumulative updates] first.
Then install Service Pack 2 for WSS/MOSS; after that install Service Pack 2 for the Language Pack(s).
