Having the same issue with Acrobat Reader 9.3 and Windows 7.  Cannot open a PDF from a web browser.  Any solution?

Sorry

I upgraded to reader 8.2.4 and it seems to be fixed.

The thing is we can't afford to upgrade from Adobe CS3, which comes with Acrobat 8.  But we don't have enough licenses to make it the default pdf viewer.  Won't acrobat reader 9 conflict with Acrobat 8?

I changed the file association for pdfxml to Acrobat 8.1 (it was Reader 9), and this fixed my problem.  I also have Win 7 and IE 8.

IE8 ->Tools -> Options -> Programs -> Set Programs -> Associate a file by extension

There's probably a shorter route through control panel.

I was told to upgrade to Acrobat 9 to fix the issue. By the way, we use software that we've spent ££££ on previously that was designed for Windows 95; and it WORKS 100% with Windows 7 without the need to spend money. This makes Adobe software look crap.

We had no choice but to look elsewhere - I found NitroPDF who told me they were overwhelmed with sales from people in the same position as me. So we purchased NitroPDF Pro for the entire business, saved £££ in the process, and it works better than Acrobat did. It also works with Windows 7.

I'd urge anyone else to consider doing the same.

This was previously posted and it worked for me in Reader 9.4

Easy fix:

1. Open Acrobat 8**

2. Go to Edit > Preferences > Documents

4. Look at the "Save Settings" area

3. Uncheck "Save as optimizes for fast web view"

Relax and enjoy the raise the boss will now give you.

WOW, I think the suggestion from ItsOkayNow helped, I still get Acrobat professional opening with the error message, "Cannot use Adobe Reader to view PDF is your web browser.Reader will now exit. Please exit your browser and try again."

So far, however, it seems to open the PDF file every time and I only get the error the first time for each browser session.

I am running Windows-7 64bit and using Internet Explorer 9, and first an update for Adobe Reader arrived 9.4 - suddenly any pdf file on the internet caused an error on IE. I returned the Adobe reader back  to V9.1, and was back in business again. Next I was offered an upgrade of Acrobat 9 pro to Actobat X pro, which I took. Wonders upon wonders, trying to load the new software (from disk), it deleted my old software, fine - then when it came to verify the upgrade via the web, it would not accept the serial number of the old version. Although I asked that the new software not be the default program for pdf files, it corrupted the reader, and back to square 1 - errors. As a part of the procedure to register the new version (before I realised it was completely corrupted) I was sent to the Acrobat X page of Adobe - no go - couldn't see the contents, which I assume was a pdf file. I have now cleared all the new versions of reader and Acrobat X pro, and reloaded the old version of Acrobat 9.4.2 - all OK now. BUT, I have paid for the new wizz-bang version, and am unable to use it. What now?

My environment is:

64bit Windows-7

Firefox 3.6.16

Adobe Reader 9.4

ASP.NET 3.5

ReportViewer 2008

Was unable to open a PDF file under both the browser and reportViewer as I had previously. Received an all black then all blank screen. Uninstalled adobe X flash product and the Adobe plugin for Firefox and Waalaa .... Everything works.

Delete all about Adobe acrobat professional package

[HKEY_CURRENT_USER\Software\Adobe\]   just delete the (Acrobat Reader\8.0) only

[HKEY_USERS\S-1-5-21-2690979374-15258355-172494975-500\Software\Adobe\ Acrobat Reader\]

You may found another problem after fixed Fault 1:

Fault 2: Cannot create PDF by Adobe PDF maker add-Ins
Reason: Adobe acrobat professional 8.0 add-Ins mismatch with Office 2007/2010
Solution:
For Office 2007, update Adobe acrobat professional 8.0 to latest version, problem will be fixed.

For Office 2010, adobe didn’t create any update batch for Adobe acrobat professional 8.0 to support Office 2010, so if you using Office 2010 and Adobe acrobat professional 8.0 ,you must create PDF by Microsoft Office 2010, just install Microsoft  “SaveAsPDFandXPS” add-ins, save as PDF, then you can use Adobe acrobat professional 8.0 to edit the form.

^^

Hmm - Didn't work for me. But here is what did in Firefox: (Although I did uncheck the two INTERNET boxes in Acrobat.)

In Firefox go to TOOLS > OPTIONS > APPLICATIONS > CHANGE ACROBAT "ACTION" TO "ALWAYS ASK"  Then when a PDF opens the first time and asks what to do? Select Acrobat and checked the "Always do this box"

There seems to be no problem like this with IE 9.

Cheers!

It's unfortunate ut is still an issue. I haven't had the problem since I did what I noted in my last post.

The basic issue is that Acrobat 8 has not been updated to run under Windows 7. Even if you can get it to work sometimes the program was never designed to work under Windows 7. Further Acrobat 8 is not longer being supported by Adobe as it is past its cycle lifetime.

You need to upgrade to a newer version of Acrobat/Reader.
