OFFICE 2007 AND ACROBAT 8    
I have recently discovered (to my chagrin) a poorly documented feature about problems with Acrobat 8 and Office 2007. When I installed Office 2007 on my laptop--after oh so efficiently uninstalling Office 2003--I began to have major problems with converting Office documents into pdf files. In short, I couldn't convert Office documents into pdf files!

So I went the Google route. Three of the resulting links are included below.

This hassle all stems from a battle between Microsoft and Adobe over the pdf option Microsoft wanted to include in Office 2007. At some point, there will probably be a patch, but in the meantime, here is my suggestion: If you plan to use Acrobat 8 frequently, don’t install Office 2007 until the patch is available, OR if you still want to install Office 2007, be prepared to download the add-in from Microsoft at http://tinyurl.com/2v77sn. Somebody said that this add-in is already included in some versions of Office 2007.  More confusion.  If you have this add-in installed, when you have a Word document you want to make an interactive pdf form, you won't find the Adobe PDF buttons on your toolbar to convert the file, but you can save the file as a pdf document, open it in Acrobat, and then make it an interactive pdf form.
 
And be aware of other problems in the Office upgrade. While I am on a rant (bias openly stated), I’ll just mention that although Acrobat 8 is a wonderful upgrade, Office 2007 is tediously exasperating. Although there are many new bells and whistles that make me say, “Ahhh! Neat!” there are more occasions when I’m searching for the cleverly hidden new location of the command I need in a hurry and my reaction is “Arrrrrgh!”
