OS X killed Microsoft Office for Mac 2004

After installing Mountain Lion, my Microsoft Office Suite would not open. I found this post, but don't understand it:

There is actually a fix for this. Check the individual OS forums - many people had this problem with the recent security update. If you installed the security update, make sure you do an software update again.

What is "individual OS forums" and how can I find this security update / software update so I can open my apps again?

BTW: After installing Mountain Lion, I got this message when I tried to open up Word or Excel: "power PC applications are no longer supported."

I would believe them.  In 2004, there were no Intel powered Macs.  You will probably have to get a newer version.

There is NO support in OSX 10.7 (Lion) and 10.8 (Mountain Lion) for old PowerPC applications.  They simply will NOT work.  The last version of OSX to allow you to run PowerPC applications was OSX 10.6 (Snow Leopard).  OSX 10.6 included a system component called Rosetta which provided the code to allow old PowerPC applications to run on Intel processor Macs but it was dropped with 10.7 and there was / is no alternative to it.

You've a couple of options .. though none are ideal.

1. Try Open Office (as that post you provided recommended)
2. Reverse the upgrade to 10.8 and go back to 10.6 (using a backup)
3. Upgrade/buy a newer version of MS Office 2008 or 2011
4. Use a VM such as Parallels, Fusion or Virtual Box to run Windows with MS Office.
Hi brucegust,

You upgraded from MAC OS X 10.6.8 (or 10.6.6)? They could open powerpc applications. Since MAC OS X Lion (10.7). This is no longer supported.

If you want to use Microsoft Office Suite, you will need to buy the latest Microsoft Office Suite. But you can also install Open Office (it's free). So you can open and edit documents (also Excel, ...).

Thanks for the bottom lines, folks! I'm going to get an upgrade to a new version of Microsoft Office for Mac and we'll go from there. I just didn't want to spend any more money until I new that was the thing that needed to be done.

Rock on!
