PDF pages don't appear in web browser (Adobe Reader 9)

I just installed Reader 9, and now when I click on a link to a PDF on a web page I get this message: "The Adobe Acrobat/Reader that is running cannot be used to view PDF files in a web browser. Adobe Acrobat/Reader version 8 or 9 is required. Please exit and try again." Since I AM running version 9, this seems abnormal . Any ideas?

Use these reg keys to fix this problem. Copy and paste the text below into notepad and save it as "AdobeFix.reg". Double-click the saved file to add the entries into your registry.

Open Reader 9.0 . Open "Edit" then " Preferences" then "Internet" from the list on the left then deselect "display pdf in browser" hit O.K.

Now it will open it directly in to a pdf instead of trying - and failing !!- to open it in a new browser.

Had the same problem myself i am using Windows XP+Firefox3

1. first check your file association for pdf
   
2. If the files association is correct then uninstall the arcrobat reader9 by going to add/remove programs in control panel.
   
3. reload arcrobat reader9 install file from adobe.com
   
4. reinstall & restart your computer

That should be it, if using firefox3 go to tools/options/applications tab and change the action column against adobe acrobat listing on the left.

Good Luck

Some bug in the installation sometimes fails to include the path to the reader application in the Registry.

IF you need to open PDFs in your browser :

• Got to Start - Run - enter "Regedit"
• Browse to HKEY_Local_Machine \ Software \ Classes \ (you may have to create the following keys) Adobe \ Acrobat \ Exe \ : Change "Default" to "C:\Program Files\Adobe\Reader 9.0\Reader\AcroRd32.exe"
• It should show up in regedit like ""C:\...""

This will fix the issue, by telling the browser where to find Adobe Reader.
