Reader 9 won't open PDF from web browser

I had the same problem.

I had both Acrobat Reader and Acrobat.com on the list of programs. Apparently Acrobat.com is also Reader. I uninstalled both of them and then reinstalled Reader. Solved the problem.

I rebooted after each uninstall, although I don't know if that is critical.

I had the VERY frustrating issue of not being able to open a PDF in a browser window after installing Acrobat Reader 9. Looks like the problem was rooted in the fact that I had a browser open when installing Acrobat Reader 9, which seems to confuse things.

Solution (as above):
Uninstall Acrobat Reader. Make sure all browsers are closed, then re-install.

Suggestion for Adobe: if you need us to close all browser windows when installing your software, then make us do so! It took me nearly two hours of my workday to fix this issue!

Hi Noel,

The advantage of opening pdf's in the browser is that all our internal users are used to pdf's opening in the browser. If I change it to open in Reader they all start asking questions.
When I try to open a pdf file from the referred site "http://www.nza.nl/aanbieder/GGZ/12364" Adobe Reader opens and gives the error: "An error occured opening the document. Cannot find the file." This is with Windows XP SP2, IE6 and Reader 9.

I solved the issue now by opening op DNS to internet for the internal network, but why Adobe changed the way it handles PDF files in IE I don't know...

I am using IE 7 and had downloaded Reader 9.0, but was unable to get it to work on the Web despite trying the suggestions I found here. I finally gave up, uninstalled 9.0, dowloaded 8.1.2, set it to not open a .pdf in a web browser window, and now I'm rolling.

Thanks for all the help.

I haven't noticed this problem. I guess it's been fixed.

For those of you who followed Kuba's instructions regarding creating a registry key and found it didn't work, make sure the path in the registry key matches the path to where you have Reader9 installed.

Thanks for the reply.
But this isn't a solution. It's a workaround.

There are too many websites that can't handle PDF's not opening in the browser, like: http://www.nza.nl/aanbieder/GGZ/12364

And because the option is in Adobe Reader, it should work.. right?

If you have Adobe Acrobat 8 and Adobe Reader 9 installed on your computer, both may be attempting to open PDFs in your web browser...

One simple resolution, as suggested by alvand is to open Adobe Acrobat, go to Edit > Preferences > Internet, and clear the "Display PDF in browser" check box.

This should solve the problem.

I think these problems are the same, can anyone help me with this?

Thnx

Kuba you rock. #54 is what I used for a solution and my test station worked great. I'm setting Reader 9 to redeploy. Oh this is great! Thanks again!
