We had an issue at work where on any computer with Acrobat Professional installed Word 2007 would run really slow. Opening, closing, saving, and creating new documents all took 3-4 seconds during which the entire computer would lock-up and the processor would be at 100% utilization. Even switching between programs would seem to do this.
A quick Google for Word 2007 lockups didn't turn up much other than a few references to the Add-ins menu, so I checked that out and found one for Acrobat PDFMaker Office COM Addin which didn't really seem necessary. Turning it off instantly gave Word the excellent performance that I expected. Here's how:
- Click the Office button in the top left, and go to "Word Options" (bottom edge of the menu).
- Select "Add-ins" on the left, and notice the "Acrobat PDFMaker Office COM Addin" under "Active Application Add-ins."
- Towards the bottom of the dialogue you will see "Manage:" followed by a drop down menu. "COM Add-ins" should already be selected.
- Click "Go" and on the next screen uncheck the box next to the "Acrobat PDFMaker Office COM Addin."
- OK your way out of the all the menus, and you should have improved performance without even restarting Word.
