First direct link in google search causes "Internet Explorer blocked this site from downloading"

Question

I've disabled both the Adobe Reader Add-on and the Adobe PDF Link Helper to force IE 8 to open PDF's outside of the browser i.e in the stand alone reader application.
After doing this I did some testing, a google search for "test pdf" produces numerous direct links to pdf files.  If i click any of them it causes IE to display the message bar "Internet Explorer blocked this from downloading files to your computer, click her for options.."  When I click on the message bar, it appears to download the file , then nothing happens.  Next time I click the link it opens in the stand alone reader just fine and so do all PDF files, until the browser is restarted or a new tab is started.
This only seems to happen in IE8.  IE9 doesn't have the problem.
If I open a web page that has a link to a PDF that always work.
Help? I can't roll this out to prod.  Users will get very confused...

Answer 1

You actually trashed the whole Internet Preferences Folder including all your preferences still in there?
Actually, you were suppose to just trash the Internet Preference file/document which is inside the folder.
See if updating to the latest & last version of IE for Mac will help.
Internet Explorer (Classic) 5.1.7
Internet Explorer 5.1.7
Internet Explorer v5.1.7
"WARNING:" Microsoft ended support for Internet Explorer for Mac on December 31st, 2005, and is not providing any further security or performance updates.
Accordingly, as of January 31st, 2006, Internet Explorer for the Mac is no longer available for download from Microsoft.
Or, you can try the following w/your older version of IE:
Once a week Go into the system folder>preferences folder & trash the following preferences:
finder
ASLM
PPC Registration Database
Cache.waf-found inside the MS Internet Cache folder
MRJ Cache folder-a new one will be recreated.(If not found go to System folder>Application Support>MRJ Cache folder-trash all you find inside-(DO NOT TRASH THIS FOLDER)
Download Cache-found inside Explorer Folder
Downloads.html-found inside Explorer Folder
History.html-found inside Explorer Folder
Rebuild your desktop w/extensions off. Use Techtool Lite or Trash*Desktop - may delete Finder comments to rebuild your desktop w/extensions off. Does a better job than manually & you avoid all the finger gymnatics. You just have to hold down the shift key to shut off extensions.
Restart to turn the extensions back on again & empty the trash.
Good luck!
