Web browser opens PDF files with Acrobat 6.0 instead of Reader 9.0

Posted on 2010-08-19
Last Modified: 2013-12-08
We have a Windows XP workstation that has Adobe Reader 9 and Adobe Acrobat 6 installed.  Reader 9 is set to open PDF files from the local machine ie when the user double clicks on a PDF file on his desktop, the file opens using Reader 9.

However, when he tries to view a PDF file on IE, it tries to open the PDF file using Acrobat 6.  I am not sure how to configure the browser to open the PDF file using Reader and not Acrobat.

Any ideas would be greatly appriciated.  BTW, we can't uninstall Acrobat 6 to upgrade, funding is not available right at the moment.

I might be wrong but, I think the problem is that Acrobat 6 was installed first. Try uninstall and then re-install Acrobat. Then see if it does the same thing. I know it seems an extreme measure, but if you have two exe's with the same name in different locations, if you type the exe name in a run box it will open the first one installed. Worth a go...

adallen is right but, you have to make sure you do the same in acrobat 6 and untick the Internet option...

Uninstall should not be necessary.

If you untick the internet option in both Reader and Acrobat then a PDF will not displaly at all.  Am I missing something here?

Sorry I misread adallen's post as I guess he mistyped it.

You have to select it in A9 and deselect it in A6.

It has bee my experience that the dll in question is the AcroIEhelper.dll that is found at:

c:\program files\common files\Adobe\Acrobat\Activex\

Here is how I would approach fixing this issue.

Uninstall Adobe Reader 9.   Do not reboot just yet.
Open up a command window and CD to c:\program files\common files\Adobe\Acrobat\Activex\
run this command:  taskkill /f /im explore*
That should kill all explorer.exe windows.  Your desktop and task bar will disappear but the command window should still be open.

Then delete the acroiehelper.dll file (del acroie*.dll)
Then you can run explorer.exe again just type in:  explorer /separate
Then reboot.
After the reboot, reinstall Adobe Reader 9.
That should replace the AcroIEHelper.dll from Acrobat 6 to Reader 9
