Reader 9 won't open PDF from web browser

how do you install v8? I can't find how to do that? It keeps trying to install 9

I finally got PDFs to work in my browser by doing the following.

1. Uninstalling Reader version 9
2. Installing Reader version 8.1 from the abobe.com website
3. I then had to uninstall via control panel add remove programs the adobe.com program, and I also uninstalled the Adobe AIR program.
4. I then checked in my Add Remove programs list and Adobe Reader 9 is still listed, I uninstall it again (why I don't know).
5. I then view a PDF file outside of Internet Explorer and I have to accept the license agreement in a popup window to get Reader 8 working properly.
6. I then go to a web page that links to a PDF file and finally I can view PDfs in the browser again.

We have around 30 PCs in our department with Adobe Reader 9 and some of them work in a browser and some of them do not, so there appears to be a conflict of some sort.

For info, I have Acrobat Professional 8.1 on my PC also.

Good Luck

I am having the same issues. The problem was that I did not close down all the browser windows in IE and Firefox, before I started to install the Reader. Uninstall the Reader first, then make sure no browsers are open and reinstall the Reader. It should do the job.

Unless of course you really need your PDF to open in your browser, then that solution is absolutely useless. Yeah, it may stop the error message, but your PDFs will open in Adobe Reader program instead of your browser. Some PDF forms and applications require IE's Active X or other browser based technology to fully function.

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.

well, I had the same problem and solved it
in adobe 9 (or acrobat ) go to edit>preference>internet
and uncheck the "Display pdf in browser"
then press OK button and exit the program

again open the program and go to same path and check "Display pdf in browser" then press OK button and exit the program

It will solve your problem

Thanks to # 32 Marc. I had the same problem. I couldn't open PDF's from the Web. I uninstalled, re-started my pc, registered, and re-installed. It works!!!! I have Vista X64, SP1. Many thanks.

Hope this works for you also.

I am preparing to deploy to 3000 company PCs and 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." is NOT going to work.

I can't use a "one computer at a time" solution.

I have Windows XP and after updating to Reader 9 I received the same 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."

It is too bad Adobe doesn't simply tell you to register after installing Reader 9. I registered and now I can open pdf's. Thank you post #32 for the suggestion. It worked for me.

I had installed Adobe Reader 9 a couple of days ago and opening PDFs in the browser window in IE 7 worked great.

Yesterday I installed an old version of Adobe Acrobat.

Today I tried viewing PDFs in the browser and got the same 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."
When I clicked on OK a blank Acrobat window popped up and the browser showed "Page cannot be displayed."

This fixed the problem on my computer:
1. Control Panel -> Add Remove Programs -> Adobe Reader 9 -> Remove
2. Restarted the computer.
3. Tried opening a PDF in the browser window.
6. Clicked on Open on the Open / Save prompt.
7. Allowed Microsoft Search to look for an application.
8. In http://shell.windows.com/fileassoc/0409/xml/redir.asp?EXT=pdf clicked on the Adobe Reader link.
9. Followed instructions to install Adobe Reader 9 again.
10. Opened Adobe Reader and clicked on Accept on the licensing screen.
11. Restarted the computer.

I have the same problem with open PDF files on the web sites

I work for 3 hours and I find the solution ...

I re-download the 9 version of PDF and I " REGISTRED " this free version and now ... I can open the PDF file on the web site !!!

I think the no-registered is the object of the problem

Try this and good lock
