the acrobat reader that is running cannot be used to view PDF files in a browser

HI i'm new and i have problem is that look i want to eliminate adobe readeer 8.1.2 to installe again but when I try to supr appears this "no se puede eliminar la clave \.rmf. compruebe que dispone de suficientes derechos de acceso a esa clave o pongase en contacto con el personal de soporte tecnico" is in spanish the problem is that adobe can'tunistalled and i don't how to unistalled the program thaNKS FOR YOUR ATTENTION

I've tracked down one possible solution. YMMV.

In the Adobe Customization Wizard 9, on the Installation Options page, there are three choices for "Default viewer for PDF files":
*Installer will decide which product will be the default
*Make Acrobat the default if both Acrobat and Reader are installed.
*Make Reader the default if both Acrobat and Reader are installed.

If I leave it as Installer decides (top), it seems fine. If I choose Acrobat (middle), I get the error. I'd been choosing Acrobat under the assumption that someone with Acrobat 9 might elect to install Reader 9. And I do prefer sentences that end with a period. ;)

This is on a virtual machine with XPSP2, no Adobe products (other than Flash 10 and customization wizard), .NET 2.0, Windows Installer 3.1, MSIE 6, and a few other products. Neither Reader nor Acrobat prior to install -- clicking on a PDF in MSIE would offer to download the file.

Ashley,

We have had the same issue you are having. I have also used Adobe's customization tool and made a transform. However after that we had to open that transform in Wise Package Studio (we use it for all MSI packaging) and add the registry keys from Solution one to solve this problem. This worked for us. Procedure is basically to create this key manually on a test PC and make sure that it works. Then export this key from the registry and go to Wise Package Studio, open previously created transform and select HKEY_CLASSES_ROOT and right-click to import .REG file. At this time point to your exported reg file and you will be asked to integrate the registry keys properly by Wise Package studio. Accept that change and save your new transform. This worked for us.

I am using the Adobe customization tool to make a transform for the .msi file for an automated install. It looks like the registry information referred to in Solution 1 in the above KB is not being written to the registry. There is a different entry in the .msi, but nothing gets generated.

When I attempt to add the key via the transform, it fails to add anything. When I add it using a reg add command (or manually), it works.

Kind of reminds me how Adobe Reader 8 totally horked up the registry permissions so that Adobe Acrobat Pro 7 would fail to install unless a Microsoft tool was run to reset the permissions. Plainly visible when looking at the .msi using an advanced msi editor.

Remember when we could trust these guys? For what they are getting for an Acrobat Pro license, this is inexcusable.

Go to the Support page of Adobe website and enter "the acrobat reader that is running cannot be used to view PDF files in a browser" or knowledgebase ID "kb405461" in the search box. TechNote on the issue and solutions will be provided.

I was able to open the document directly from Acrobat/Reader, bypassing the browser by following Solution 2.

Good luck!

I got the same error message - complete rubbish to have released it without testing this. Anyway, I deleted Reader 9 and reinstalled 8 and updated it, still got the error message, so followed the suggestions here from Gene and deleted the left over Adobe Reader 9 folder in the Programs folder. Works a treat now and opens in the browser - I don't want to have Reader files having to open outside the browser - how messy is that.

I AM DEAF DUMB. YOU HELP GIVE ME VIEW PDF FILES IN A WEB BROWSER ADOBE ACROBAT/READER VERSION 8 OF 9 REQUIRED. PLEASE EXIT AND TRY AGAIN.

Bob..try the solutions in this TechNote:

If you have uninstalled Reader then you need to go to C://Program files/adobe/....and delete all the leftover folders. Then when you reinstall you will perhaps have better results. You probably have folders left from your previously installed versions as well. (which will give you an opportunity to complain about the shoddy Acrobat uninstall). If all else fail go to your Preferences in Reader and on the left click on Internet...then on the right UNCHECK Display PDF in Browser. This will cause all online pdfs to open in the Reader program instead of the browser. No doubt you will find something lacking in this solution as well. Best of luck!

The Adobe Acrobat/Reader that is runing con not be used to view PDF files in a Web Browser Adobe Acrobat/Reader version 8 of 9 required. Please exit and try again.

The funny thing is I used to have a bad opinion of Reader 4 and 5, using Foxit and special plugin strippers then available. With the last couple of versions of Reader I thought they'd got there act together - they worked fine in IE7, Firefox 3 and so when I saw Acrobat Reader 9 was available I installed it immediately - big mistake.

I suspect they'll get it fixed sooner or later but in the meantime ... I'm glad I kept a copy of the previous version's installer. (I did notice that with previous version 8 checking for updates available did NOT say anything about version 9)

Sadder, but wiser ... back to version 8 :-[

Edit add: just checked ... if you have add-on IE View it appears that PDFs are displayed just find (and quickly) in it!
I guess maybe I will leave Adobe 9 installed for the time being.
