Outlook 2010 PDF Handler
For several months I have been getting the message in Outlook 2010 that there was no PDF Handler. I decided to do something about it today. I tried for about an hour. One of the steps I took was to “repair” Office. That required me to restart my computer, something I seldom do because of how long it takes to do so, even with a Core i7. The repair didn’t solve anything.
One thing I read online was to go into Adobe Acrobat reader and make sure some check-box was unchecked. When I opened it up from the start menu, it starting going through some finalizing installation steps. That seemed strange since I have been opening PDFs for some time now. I guess opening it directly is slightly different than opening the program by double-clicking a PDF file. I got to the check-box and it was already unchecked.
I opened Outlook again, and my PDF Handler worked! Apparently all it took was opening Adobe Acrobat Reader XI from the start menu. What a crazy simple fix!

Oh no, That probably means you have Adobe Acrobat installed into every office product too. It might be contributing to the reason your computer takes so long to boot!
