After I installed Office 2010, I noticed that the Acrobat ribbon was missing. I went to the Adobe website and learned the story. It seems that in versions of Acrobat 9 before 9.3, the Acrobat ribbon didn’t work right with Office 2010. Adobe came up with a fix in the 9.3 release: they removed the ribbon. Clever, huh?
Without the ribbon, there are a couple of ways that you can make pdf files, but none of them are as convenient as using the ribbon. If you make a lot of pdf’s, and don’t need any Office 2010 features right away, you might as well keep on using the previous version until Adobe sorts this out.
