Adobe Reader could not install correctly on Mac OS X
First of all, I just noticed Adobe has changed the name of Acrobat Reader to Adobe Reader...
Today when I run Adobe Reader for the first time after I installed it on Mac OS X, it says:
"Adobe Acrobat could not install correctly. Adobe Acrobat was unable to install and must quit."
I googled around and found the following link very helpful:
I recall days before I deleted all printers' drivers from my Mac... and the whole /Library/Printers folder. After recreate an empty /Library/Printers folder, Adobe reader goes normal.
