I solved the problem by downloading a different free pdf reader program. It also allows me to create as well as view. Problem solved. I also noticed that there are a huge number of people having the exact same problem and no one seems to have a good fix for it.
Not sure why it has worked for years and the minute I click on the update button all was lost but after two days of being unable to send out quotes, I just couldn't keep trying potential solutions with no resolution. When even restoring your computer to a prior date doesn't fix the problem then that is not good.
May I ask what the alternate PDF reader program is/was that you installed. I am one of the many unfortunate others who upgraded the Adobe Reader program and now encountered the same conditions/errors. Totally Frustrating/Annoying. One has to assume that the current version wasn't fully developed/tested to insure installation & use would be problem free. Your support would be most appreciated.
When the core library does not work anymore, Acrobat / Reader can no longer run because the components it depends on do not load.

I have the same problem, following an updt applied shortly befire 6 Apr. "Acrobat failed to load its Core DLL"
HOWEVER , if I open a CLI windows and at the prompt enter:
Acrobat Reader opens fine and normal and I can open any .pdf file on my harddrive including ones I created at Kingsport Press under Acrobat Distiller 3.0 years ago.
The laptop was bought in Spring of 2008 and has had numerous updates applied over the years. The AcroRd32.exe is version 9.5 and op sys is Windows Vista.
