Reader 9 won't open PDF from web browser

Disabling the "display in web browser" under Edit>Preferences>Internet in Reader 9 worked for me. However, I have Adobe Acrobat Pro 8 installed and the downloaded file opens in that program rather than in Reader 9.

I have a Sony VAIO with VISTA and experienced what others describe.

As soon as I updated to Adobe Reader Version 9, I started receiving the exact error message Mary Smith described: "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."

This condition disrupted my work with LiveCycle Designer on forms I had been creating. Every time I clicked on a PDF in LiveCycle, the error appeared and my LiveCycle Designer program would report it had to shut down.

The solution: what everyone else has described. Uninstall Reader v9.0 and download/install Reader v8.1.2.

Recommendation: until Adobe fixes this condition definitively, avoid Reader v9.0. From the posts here, this is clearly an issue not worth the hassles. It's probably easiest to just downgrade to v8.1.2 and get on with your work.

I followed the advice and removed Adobe 9 reader and found that I still had 8.1 on my computer as I had purchased 8.1 Standard with my Fujitsu scanner. The problem went away. Thanks for the feedback!!!

Yep, did the same. v8 works

I have had the same problem since loading v9. I tried some of the fixes listed here but with no luck. I finally unistalled v9 and reloaded v8. Find v8 on filehippo dot com

I have installed Reader 9, but getting this error when tried to open a PDF file from brower" This action is only valid for products that are currently installed" Please tell me how to fix this.
Thank you,

I am having the exact same problem with Acrobat Reader 9 and the latest version of Explorer. I keep getting a pop up box indicating I need to have the version 8 or 9 to open the pdf AND I HAVE 9 INSTALLED!!!!

I have tried to repair the installation. I have checked the internet security section of my control panel and it is configured correctly according to what is posted on the Adobe site.

What is going on here???????? AND WHY IS THIS PROBLEM OCCURING? I should of never updated as the old Acrobat reader worked fine but now it has been removed from my system with the 9 installation.

Any help would be greatly appreciated. I now can not access information I need in order to do business on a daily basis.

Thanks! HH

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

We use to have the same issue with Windows XP SP3 (Fresh Install) & Adobe Acrobat Reader 9.0.0. I finally got it working again. For this I did some steps (one of these seems to have repaired the situation)

- Upgraded Firefox 3.0 to Firefox 3.0.1
- Updated Acrobat Reader 9.0.0 with the additional language update
- Modified in Firefox the Tools\Options\Application field Application/PDF to "Use Adobe Acrobat (in Firefox)"

Yes, I know that, but if I need to open the pdf in a browser what to do then? This option doesn't help me a lot. Even, when yo uinstall reader 9, by default this checkmark "display pdf in browser" is unchecked! In earlier versions this was ok.
The specific program I'm working with needs to open pdf in a browser (not outside it), otherwise I'm loosing my program functionality. So, that is why i can't use Reader 9, which is really more faster then it's predecesor :)
