Is there another way to safely uninstall Adobe Acrobat?
To address your problem. You say that Excel and Word can not be used to create a PDF. Does that mean you can not print to the Adobe PDF printer or that PDF Maker does not work? What version of OFFICE are you using? Have you checked to see if the toolbar icon is simply turned off?
After downloading all the updates, I was able to remove Adobe from my computer using Add/Remove. Then I reinstalled and it seems to be working. It has trouble bringing over footnotes from Word, but at least it creates a PDF now.
