Why I cannot see downloaded PDF files from the web?

I'm getting a message: "The file could not be opened. It may be demaged or use a file format that Preview (or PDF) doesn't recognize".
However my PDF is updated and it works with my older PDF files saved on my Mac.
Thanks for your help.

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 (command-V) into the text box that opens.
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.
I've seen an unconfirmed report that the "Silverlight" web plugin distributed by Microsoft can also interfere with PDF display in Safari, so you might need to remove it as well, if applicable.
Test. 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.

Bug:Downloading pdf file from the web,file name in dialog box populates with incorrect file name

Hi Gurus
When downloading any pdf file from the web using adobe Reader X the file name dialog box populates with incorrect file name
compared to the saved file name of the document downloaded.
Clarity
1. Download any pdf file from the web
2. Click File, Save as note the populated File Name
3. Compare the populated file name with the saved file name of the documant yuo are downloading.
4. The file Name is incorrect...
Is there any work around on this issue?Can someone please help?..
OS:Windows7
Reader: Adobe Reader X
I've tried a couple of other versions and still get the same results...

Are you downloading the file (right-click, save link as), or just opening it by clicking it?
If the latter, then what happens is the file is loaded to the temporary internet files folder by IE and assigned a temporary name, which is then used when you're trying to save it.
You can test this out by going to File - Document Properties before trying to save and looking at the file's location.

Downloading PDF files from reliable web-sites U-R-G-E-N-T

Hi,
Since last year I encounter regular (close to 100%) problems downloading PDF files from reliable web-sites (for sure web-sites from which I could troubleless download PDF files in the past) The result on my HDD : 0KB pdf file ! = An empty file
This is very anoying and I am sure I am not the only one who encounters this.
Please review your procedures and make this possible again.
Note: I uninstalled Adobe Reader, reset Safari, closed Safari, re-installed Adobe Reader : no results !
THANKS FOR HELPING ASAP !
I travel a lot and have to bring my files with me as internet is not always available in the countries where I work

Hi Christian,
I've had problems for ages with this but I did notice that after I went through the reinstall with Apple yesterday I now have a couple of different options that are working.
Yesteday I uninstalled reader, restarted my computer and then reinstalled again. I didn't think it had worked for me but after some extra experimentation I have discovered a couple of things.
On some websites eg: https://www.gatewaycu.com.au/uploadedFiles/PDF/Forms/Quick%20Debit%20Authority.pdf
it is coming up with a toolbar (I suppose it's called) at the top of the PDF and it is allowing me to print and save to my desktop, open the pdf and print YEAH.
Also with another website the PDF is showing up differently. eg http://media.wix.com/ugd/99e891_6110f024d956431abb7b66dd24f19251.pdf
This shows up like it used to but the difference is that if you try to save as or print throught the safari options like I used too it doesn't work, BUT if you hover down the bottom of the PDF it brings up a bar type box (sorry I don't know the technical word for this) then you can print, save to desktop, documents etc and then print from there too.
YEAH! It looks like (I hope) that the problem is solved. You have to go about it in a couple of different ways depending on the website, but hey, I don't think that's so bad as long as I can actually print my PDF's. It's better that not being able to access any of them which is what's been happening for the last few months.
I hope this helps you guys out and if you have any problems just let me know and I'll try and explain it better for you.
Cheers

Adobe 8 - Unexpected Corrupt or incorrect file type warning when viewing a PDF file from the Web

Hi,
On downloading a PDF file from my web site using Adobe 8 on the client machine I expect the file to open automatically however I receive encounter the "File Download" dialog. It has the following warning message: "The file you are downloading cannot be opened by the default program. It is either corrupted or it has an incorrect file type. As a security precaution, it is recommended that you cancel the download."
This issue did not occur within previously tested versions of Adobe Reader (e.g. Version 5.1).
On investigating the issue I discovered the factor that results in Adobe 8 failing to open the file automatically is the Content-Type = "application/pdf; Charset=utf-8". However, if I intercept the response and alter the Content-Type to contain only "application/pdf;" the issue on Adobe 8 does not occur.
I have even tested when the Content-Type contains an empty Charset (i.e. "application/pdf; Charset=") but this issue still occurs. In addition setting the Charset to other encodings (e.g. "ISO-LATIN-7", "iso-8859-1") the issue occurs.
QUESTION(s):
1. Why is it necessary for Adobe 8 when opening PDF files from the web to expect no Charset within the Content-Type?
2. If this was not an issue within previous versions of Adobe surly this is a bug?
Since I cannot ensure that the Response's Content-Type does not contain a Charset at all please can someone suggest either a work-around or more importantly a solution to the issue?
Please Note:-
1. Within Adobe, Edit -> Preferences -> Internet option it's compulsory for our users to have "Display PDF in browser" ticked!
2. We cannot prevent a Charset from being present within the Content-Type of the response sent to the client, hence this issue.
Many Thanks in advance,
Martin.

Bill,
This is exactly the same behavior I observed when I rendered a PDF stored in a database through a .NET page. If I chose to save it, it would open fine after the save, but if I chose to open it in the browser without saving it, I would get the error.
The problem was not with the PDF or Acrobat. It was with the way I was delivering the PDF. Putting the following code before my binarywrite fixed the issue completely:
Response.ClearHeaders()
Response.ClearContent()
Response.ContentType = "application/octet-stream"
Response.AddHeader("content-disposition", "attachment; filename=" + saveFilename)
where saveFileName is the name you want to give the PDF.
You can use 'inline' instead of 'attachment' above if you just want the PDF to open (no option to save first). You can also use 'pdf' instead of 'octet-stream' (not sure the difference).
The trouble seems to be that .NET puts some info in the header and/or content by default prior to anything your code says to write. If you don't clear this, IE has an issue with it. Other browsers seem to ignore it.
Bottomline is that this is an issue the website programmer needs to fix and is not something the user can fix by changing some setting(s).
I hope this helps.

Lately pdf files from the Web do not display properly; what is wrong and how can I fix it so I don't have to use IE?

I am a professor and frequently need to open pdfs of academic journal articles from electronic databases. Within the last two or three weeks, when I try to do this using Firefox, only the first page of the pdf displays and the rest are blank. In addition, a bar appears across the top with the message "This pdf file may not display properly." So I have had to switch to Internet Explorer to open the files and do my research. What is going on and how can I fix it so I can open pdf files from the Web in Firefox and have them display properly?

My question is simple - why would you put an application in production that has a lot of bugs? To replace a good and steady Adobe product? My customers will believe that I put a pathetic fallible form online. They are not sophisticated on computers so I just tell them to use IE. Ugh
I must agree with pgwebgirl!

When i download a file from the web i get "Anti-Virus Program not found " message. This has been happening since I change anti-virus programs for CA etrust to Sophos. How do I get Firefox to recognise my new Anti-virus program?

every time i download a file from the web (ie. a PDF file) i get "Anti-Virus Program not found " message. This has been happening since I changed anti-virus programs for CA etrust to Sophos. How do I get Firefox to recognise my new Anti-virus program?

That is a very good warning provided by the Download Statusbar extension. Something like that should been built into Firefox. I filed this Bug report a couple of years ago, about the lack of a warning like that. <br />
https://bugzilla.mozilla.org/show_bug.cgi?id=480855 <br />
I have looked everywhere that I can think of to find a list of '''IOfficeAntiVirus providers''' ''(as mentioned in the Bug report)'' that will work with Firefox, so I can't answer that for you.
You might want to ask the developer of the Download Statusbar extension about it. He might know which AV programs are compatible with the Windows API that Firefox uses for the download scan. <br />

I have to download a file from the web and copy it to the file system (ex: download from http://172.26.20.22/test.csv to \\server01\teste.csv).
I must do this using only pl/sql and java sources, I have to do this calling a procedure from pl/sql and the server doesn't have any component installed.
I've built a java procedure using java to download the file, but it give-me AccessControlException when trying to download.
Can anyone tel me what permissions I should have to accomplish this? Is there any other easier way?
Thanks.

? Some pdf files from the web will not open, some will.

Some pdf files from the web will not open, some will. I am using Adobe Reader 10.0.1 on an 8-year old puter I have just upgraded to 2G of RAM. It worked fine before with 256K. When a file won't open I get error message "There is a problem with Adobe Acrobat/Reader. If it is running, please exit and try again (103:103). Have uninstalled and reinstalled all Adobe products several times. Ideas?

Good luck with that. Adobe10.0.1 is a bug infested BAD program. Look at the posts relating to this issue for the last 3 days. Many, many problems. Support is no help.

I apparently got stung with the Adobe flash virus. Now I cannot open any .pdf files from the internet.

I apparently got stung with the Adobe flash virus and now I cannot open any Adobe .pdf files from the internet. Fix?

Go to F_Secure's Flashback Removal Tool web page, download their Flashback trojan detection/removal tool, and follow the instructions you find there.
Also install the latest java update which also tries to remove these trojans.
Java for OS X Lion 2012-003
And only download the adobe flash plugin from the adobe site.
Update:
Just because you cannot download pdf may not be an indication of the trojan. There's been a number of reports about problems like that with pdf's. Look at the More Like This section on the right side of this page.

Issue with opening PDF files from the web Acrobat 8.1.4

Hello everyone
I just found out about this problem today, and it manifests in such a manner that when you try to open a PDF document on the web, it hangs for a while, and then the standard message about Adobe Acrobat not being able to open the document comes up, and after you OK away that you get the message that the program shuts down.
If I download the PDF itself and open it locally it works. Is there any known issue with updates recently that creates this problem?
The system is running on Windows 7 32-bits, and Adobe Acrobat is a part of the CS3 Master Collection.
Greetings from Alexander

Not supported file type can (but not always) mean the PDF was created with an old enough version of Acrobat, that it isn't comaptible with reader X or XI.
Might have been damaged is pretty cut and dried in its meaning and interpretation.
There's a known issue with Mac OS and Safari Browser "breaking" PDFs as they download, but it's not so common for Windows. Since these are files you already had, it would be even less applicable.
You can try downloading an older version of Reader to check if it's a compatibility issue, but you'd have to uninstall the latest to do it and it'd be a lot of bother if they still don't open. It would also mean they are "broken" and cannot be repaired, that I know of.

I can I block download PDF file on the web.

On the webpage, Showing PDF file using <object> element.
I want to block download file.
but reader support download control.
How Could I do block control?

To view any content from the web, it is first downloaded. So what you wish for is already impossible if they can see it.

How to download a file from the web

Say, a PDF.

Hi!
Your question is marked as a Firefox OS question which is Mozilla's own mobile operating system. Thanks for contacting Mozilla Support!
It seems that PDFs cannot be downloaded from the web at this moment, however there are apps from the marketplace you can download to open already downloaded PDFs available on your microSD card.
