That’s right, even Microsoft can’t get their own data format right.
Readers commented on an article about 2008 Service Pack 2 that it broke their existing OOXML files:
I am having EXACTLY the same problem. It seems that any .pptx file created on my mac will not open. All .ppt files open fine. All .pptx files created on a PC open fine.
But, everything I was working on this morning no longer opens….what am I going to DO? I am totally screwed, can’t work at all……
Microsoft’s recommended fix? Un-install and re-install Office, but don’t do the updates. Re-create your files in their older non-OOXML formats.
Sure, they’ve now released a fix, but you have to wonder how something like this could get all the way through to the service pack. Oh wait…
