I am running on Mac OS X 10.8.2.

I have a licensed copy of Microsoft Office, and haven’t had a problem using it, until a recent update!

Since then, whenever I try to open 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?

  • Can you check the exact version of Word? Go to Applications -> Microsoft Office -> Word and right click and press Get Info. It should be something like 14.3.8 or 14.3.9 Dec 5, 2013 at 15:52

    I suggest you try to reinstall it.

    Was the recent update an update to Office or Mac OS X?

PowerPC applications were allowed on Intel Mac with Rosetta. Rosetta disappeared with Lion, if I remember well (There were 2 OS between Mavericks and Snow Leopard). The solution is either get a new version of Microsoft Office, or downgrade your Mac OS X.

    Although this answer is true in itself, it doesn't help the OP, it's a bit too general. The real issue here is that an application that worked fine suddenly turned into a PowerPC app after an update. Dec 5, 2013 at 15:36
  • Indeed, now that he mentioned what version of Microsoft Office he has, it's quite a weird issue.

  • Office 2011 was released as Intel-only. I think Office 2008 was the last build that contained PowerPC binaries.
