Office 2007 proofing

[baruche]

The original Office 2007 has a Proofing directory with English, Franch and Spanish.

In addition i have a Hebrew MUI CD that has a Proofing directory as well with he-il directory in it.

I want to copy the Hebrew proofing directory to the orig CD to have proofing for Hebrew also.

Which files i need to edit / change to make this work (if it's possible).

Thanks
