Viewing PDF files online

I recently tried to view a file online that is a pdf file but I instead viewed a window that said Unknown File Type. I have Adobe Professional installed but do I also need Adobe Reader to view PDF file online?

Just to update, i have a better way to view PDF as HTML on any phone browser. It does not need any installation!
Online version of iReader works on any phone that comes with a web browser such as iPhone, Nokia or PocketPC. Conveniently, reading can be done offline as it automatically save on your phone! It will automatic bookmark upon exit too. To use iReader, go to
http://www.doitech.com/iReader now!
Enjoy! It is a beautiful world...

Back up all data.
Triple-click the line of text below to select it, the copy the selected text to the Clipboard (command-C):
/Library/Internet Plug-ins
In the Finder, select
Go ▹ Go to Folder
from the menu bar, or press the key combination shift-command-G. Paste into the text box that opens (command-V), then press return.
From the folder that opens, remove any items that have the letters “PDF” in the name. You may be prompted for your login password. Then quit and relaunch Safari, and test.
The "Silverlight" web plugin distributed by Microsoft can also interfere with PDF display in Safari, so you may need to remove it as well, if it's present.
If you still have the issue, repeat with this line:
~/Library/Internet Plug-ins
If you don’t like the results of this procedure, restore the items from the backup you made before you started. Relaunch Safari again.

Error message when trying to view PDF files online

When attempting to view pdf files I get the following error message:
There is a problem with adobe acrobat/reader. If it is running, please exit and try again. (507:507) Per instructions found in the forum, I have reinstalled and made sure that the box for viewing pdfs online is checked. I am still getting the error message.

Please let me know the following:
1. The version of Adobe Reader on your system. You can get the same by clicking on Help > About Adobe Reader.
2. The OS you are working on.
3. The browser being used to render the PDF.
Thanks

Hi Maggy, I suspect you're using Adobe Reader plug-in, & hear it's broken in Lion,, remove it from your Internet Plug-ins folder, then try this one...

Cannot view PDF files in a Web Browser

When I click on a link in IE 7 it's supposed to open a PDF page but I keep getting error message:
"The adobe acrobat/reader that is running can not be used to view PDF files in a web browser. Adobe Acrobat/Reader version 8 or 9 is required. Please exit and try again"
However, I have Adobe Acrobat 9 Pro installed on my machine, so I think it should work. After all, it's the pro version. Do I need to download/install Adobe Reader 8 or 9? If so, why, since I've already got Pro 9 installed.
What can I do to get passed this? This task is part of an online course I'm taking per work requirements.
thx,
John

Under help there is an option for repairing an installation. You should give that a try.

Cannot view pdf files in browser

brand new imac cannot view PDF files in browser but the PDF's can be viewed if downloaded. All the data in the PDF online have question marks instead, maybe a missing font issue?

Have Adobe Reader installed? If so, disable the AdobePDFViewer.plugin resident in /Library/Internet Plug-Ins., restart, and try again. For font-associated issues, peruse Font Management in OS X

The Adobe Acrobat/Reader that is running can not be used to view PDF files in a Web Browser. Please exit Adobe Acrobat/Reader and exit your Web Browser and try again.OK. I followed the instruction and the problem still persists.

I got the following pop-up when I tried to open an online PDF file:
The Adobe Acrobat/Reader that is running can not be used to view PDF files in a Web Browser.
Please exit Adobe Acrobat/Reader and exit your Web Browser and try again.
I tried many time, and it really doesn't work.
The plug-in I have is Adobe Acrobat 8.3.0.280

After I upgraded to Firefox 5, I had the same problem and I did a work around temporarily. I went the tools menu, then Add-ons, then clicked the "Plugins" on the left side (4th one down). I "disabled" both Adobe Acrobat 8.3.0.280 and Adobe Acrobat 10.1.0.536 using the disable buttons on the right side. PDF files now open again. However they are outside the actual browser.
My guess is that Adobe didn't catch up yet with a new update to work with Firefox or vice versa.
Hope that helps!

Cannot open PDF files online with Firefox 4, help suggests foxit but don't know what that is?

Earlier versions of Firefox allowed me to open PDF files online, without downloading. Firefox 4 does not allow me to open and read PDF files online, but requires downloading to computer.
Help suggest altering settings in FOXIT READER, manually, but I don't know how to access Foxit reader, if I have it.
Can I alter settings in Firefox 4, or do I have to go back to earlier version.
Thanks

I was under the impression Foxit was a pdf viewer rather than an addon for Firefox, but maybe there is more than one application with a similar name.
I did not notice mention of foxit in the help, but add-ons are not always mentioned.

Safari & Firefox behaving badly when viewing pdf files

Since upgrading my Mac to Lion, Safari and Firefox have not displayed pdf files for viewing.
SAFARI: When I click a pdf link in Safari, a dark grey blank page appears. When I try to save the pdf file to my desktop, an error message says the file is not properly formatted.
FIREFOX: When I click a pdf link in Firefox, a white blank page appears. I can successfully save the file to my desktop, and in turn open the file using Acrobat.
CHROME: Everything works normally...no problems found when viewing pdf files.
I tried dumping the plist file for both Safari and Firefox, and resetting both browsers clearing them of cache, etc., but none of that worked.
Has anyone else seen similar behavior? Anyone have a solution?
I have posted this problem twice in Apple's Safari Forum, but have had no response in almost two months.
Thanks

In Safari you to have the Acrobat PDFviewer plugin installed, or the The PDFBrowser plugin by Schubert of Germany Installed.
If you use the PDFBrowser Plugin you need the 2.4.2 version in order to work with the version 5.1 of Safari and 2.2.3 version for Safari 5.05 and lower.
In FireFox version 3.6.X and lower you need version of the PDFBrowser Plugin version 2.2.3 which also works with Safari 5.05 and lower. And version 2.4.2 for Safari 5.1 and above and FF 4.0 and above, and Seamonkey version 2.3 and above.
THE ADOBE PDFVIEWER PLUGIN has only worked with OSX for Safari. Adobe quit supporting any other browsers on the Macintosh with the roll out of OSX years ago except for Safari. And despite repeated request by many users, its gone on deaf ears.
As a result This Schubert fellow from Germany has had to fill the void. It works on "any" browser on the Market for Mac. And works for any browser for Windows except Internet Explorer.
The only thing it doesn't do is online forms which the Acrobat Plugin will. But since it only works with Safari its Useless. I'm not going to Crank up Safari just to fill in Forms.
Oh, you use to be able to install both plugins and would work fine. Now if both are installed neither works. Its either use the one that works on one Web Browser and allows form filling.
Or use the one that works on everything, but can't do forms. Oh Schubert on his Web site explains his is forbidden from installing support for forms.

I cannot open some pdf files online with Reader XI (like sample forms in Help section).

I cannot open some pdf files online with Reader XI (like sample forms in Help section or IRS.gov or credit card statements). I have uninstalled Reader XI, cleaned and reinstalled. I have no problem right-clicking and downloading and then viewing the files. No problem viewing acrobat files. I'm runnnig Windows 7, IE9. I can acces them through Chrome.

RESOLVED
I found two suspect programs that were installed within the last 48-hrs that may have caused the problem
1) - Libre Office - latest update. This is a fork of Open Office. (unlikely)
2) - ManyCam video manipulation software (likely)
Following info here, I opted to try to open an Adobe PDF file that was on my hard drive. When I did, it refused and IE10 gave me an ActiveX error (AHA!!). When I checked the installation of ManyCam, it had installed a version of DirectX that may have over-written the resident versions or disabled them somehow.
I uninstalled ManyCam but left Libre Office's update in place, then I ran a system restore from a point 24-hrs before the installations.
This resolved the problem 100%.
So, the suggestion here is that there may be one or more program in the wild that is interupting the ActiveX or DirectX systems. They may be running or installing an older version. In this case it appears the handlers were broken.
Once the system restore had completed I was able to open Adobe PDF files within my IE10 browser from the Internet as well as open PDF files from my hard drive.
Note that this same issue also clearned up a problem I was having with the Comodo Dragon web browser, which is a fork of the Chrome project. Once I eliminated the suspect program and ran the system restore all was well. In the instance of the Comodo browser it was unable to open or reach anything - dead white screen below the menu bar.
So my suggestion would be to take an inventory of recent program installations, remove/uninstall them, run system restore from a date before the suspect programs were added, and see what happens. In my case that fixed the problem.

How to view PDF files like a flipping magazine?

Hi, I am new here. I didn't know if it is the optimum catagory for my question, I hope you guys will help me.
In brief, I want to view PDF files like a flipping magazine. You know, just the same flipping effect that ibook did on ios. Adobe reader is the only choice to browse PDF on computer for me. It's kind of bothering and annoying now.
So, any ideas for that? Plus, my computer runs on win7 64bit.

This is also a good site: http://www.issuu.com/ You can sign up and use it for free or you can upgrade(for a price) to make custom changes (like background color, button color, etc.) You can also embed the html code into your website if you would like someone to view it there. Good luck!

AdobeAcrobat/Reader that is running can not be used to view PDF Files in Web Browser...what do I need to do to fix this..

I just got Windows 7 and have been having problems since loading it. Most of my drivers only go to Vista and don't recognize 7.
I have trying to download some manuals from their website
and keep getting this message; Adobe Acrobat/reader that is running can not be used to view PDF files in Web Browser.

Could I suggest a workaround for PDFs until a solution is posted? Open them directly in the Adobe application rather than in a browser tab.
In your Adobe application(s), go to:
Edit > Preferences > Internet
Then uncheck "Display PDF in browser"
(There are very few sites where having PDF integrated is really beneficial.)

Chrome - Adobe-Acrobat/Reader can not be used to view PDF files in a web browser.

I can't view PDF files via Chrome (it works on Internet Explorer but I prefer Chrome) - the error below has arisen recently on Chrome, though I can't see what has changed.
"Acrobat plug-in
The Adobe-Acrobat/Reader that is running can not be used to view PDF files in a web browser. Please exit Adobe Acrobat/Reader and exit your Web Browser and try again."
I have looked through Forum articles on similar errors and have tried the following(text copied from other Forum entries)
Repair Adobe Acrobat (from Acrobat)
Repair Adobe Acrobat (from Control Panel
Configure Acrobat as a helper application: Choose Edit > Preferences., Select Internet on the left., Deselect Display PDF In Browser Using [Acrobat application], and then click OK.Quit Acrobat or Reader
Create a registry item for Acrobat: with Regedit: If the registry item doesn't exist on the system, do the following: Go to Edit > New > Key and create the missing HKEY_CLASSES_ROOT\Software\Adobe\Acrobat\Exe.Go to Edit > New > String Value and name this key (Default).Select (Default), and then go to Edit > Modify. Type the Adobe Acrobat path in the "Value data" for your product.,restart your computer
Repair the HKCR\AcroExch.Document registry key: Navigate to HKEY_CLASSES_ROOT\AcroExch.Document., Right-click AcroExch.Document and select Delete; make sure that you have the correct key, and click Yes on any prompts, Right-click AcroExch.Document.7 and select Delete; make sure that you have the correct key, and click Yes on any prompts. Repair your Acrobat installation
None has solved the problem. However it still works ok with IE. But I want to stick with Chrome because I find IE is so slow!
I am using Vista, with Adobe Acrobat standard 9.5.2 and Google Chrome version 23.0.1271.64 m which is marked on Chrome as 'up to date'
Does anyone know why I might be getting this error on Chrome but not IE?

I think I have discovered the answer to my own question!
I have disabled Adobe Reader plug-in, and can now see PDFs in Chrome.
(Steps: Chrome Menu, Settings option, Click Advanced Settings link, then Content Settings button, then select Disable Individual Plug-Ins, and a list of plug-ins is offered to enable or disable).
I then get a different result depending on whether or not Chrome PDF viewer is enabled - with it enabled I see the PDF document in Chrome, or with it disabled then the option is offered to download it, but either way I can get it it via Chrome without having to run Internet explorer in another browser window.
