Hi there!
Not sure if I am posting in the correct area of the forum or not, but this has been driving me nuts for weeks and if I can help someone else with this tip, then it will be worth it.
Scenario -
I had a very early version of Adobe Reader on my computer
forever. Within the last year, I have had Adobe Professional 6.0 installed on my computer. No issues what so ever when opening URLs to PDF documents.
Recently, my Adobe Reader was updated to version 9.1 (Adobe Professional 6 still installed also). Suddenly, I received an error message when opening URLs of PDF files stating that I needed Reader 8 or 9 to view the file. (Hello?? That's what I have installed!) And after clicking OK on the error message, Adobe Pro 6 would open instead of the Reader.
So, trial and error followed of all the standard check areas "open with - always use this program to open files", changing file associations (including choosing the program itself in the advanced options in this area), changing the Internet Preferences within both programs - some of which sometimes worked long enough for me to view what I needed to, but never seemed to really "stick" on an on-going basis. I have now come across this (which I am still testing to make sure it sticks) and it seems to be working.
Keep in mind that my issue only was occurring when opening PDFs from the web... Regular PDF files (emailed or on my computer already) were opening correctly with Reader 9.
Open IE - Tools - Internet Options - Programs - Manage Add-Ons...
I then selected "Adobe PDF Reader" (I didn't touch the other Adobe add-ons) and disabled it.
No, the document does not pop up in the IE framework (it opens Adobe Reader 9 in a separate window), but I personally don't care about it opening in a separate window as long as it opens the document for me to view and without me going nuts trying to get the file open
every time I opened a file in IE.
So, hopefully this will continue working and stick.
And hopefully this posting will help someone else out... Good luck!
