FROSTY This program will break your copy of MS Office 2008. After you remove the various language packages, it works fine, however, you will not be able to install an MS Office updates thereafter as the installer likes to have all the language packages there. Presumably it installs updates to the various language packages as well, and when it can't find them it pukes out.
I have tried to 'fix' the updaters by following advice from various sites that detail how to override the 'check' so that you can install the updates anyway, however, the result was that MS Word crashes on launch now.
So, use with caution.
