~ POWER PC APPLICATIONS NO LONGER SUPPORTED ~

Hello there

I am running on Mac OS X v 10.8.2

I have a licenced copy of MS Office and have not had a problem using it, until a recent Mac 'update'!

Since then, whenever I try to access it I get the following message:

"You can't open the application 'Microsoft Word' because PowerPC Applications are no longer supported"

How do I resolve this Please? Any ideas?

Cheers

Derek
