Test of ExampleSavedbyReaderX.pdf
Does anybody know why Reader X delets the signature
Regards martin

Could you please try turning off reader X protected mode and check if you continue to see the problem? You could turn off protected mode using following steps:
1. Launch Reader X and select Edit->Preferences...
2. Select General from left navigation
3. Under application startup uncheck "Enable Protected Mode at Startup"
Note: You should switch "ON" protected mode after verifying the problem. Purpose of Reader X Protected Mode is to keep your system safe from PDF based exploits and keeping protected mode OFF will leave your system vulnerable.

Latest Adobe Reader update deleted all files from my desktop - help please!

Dear all!
Yesterday I opened up a .pdf document with Adobe Reader. I clicked the Help | Check for Updates option. The reader informed me that there was an update available. I then disabled my antivirus (as is recommended). I selected the available update by checking the box next to it. I then clicked the Download option.
The update began to download. At that moment I noticed that the .pdf document was still open (i.e. Adobe Reader was still running). Knowing that the installation, when it begins, tends to notify me that it must close Adobe Reader in order for the installation to continue, I decided to close Adobe Reader myself before being prompted to do so. All was fine until that moment, as the update download and install runs in a completely separate process from the Reader, it was not affected.
After I closed the Reader, with the update still running I noticed that all files I had on my desktop were gone. None of the folders were missing, just the single files and most of my shortcuts. I checked to see if the files were just invisible or phisically missing. It was the latter. Windows Explorer showed that all files I had on my desktop were gone (deleted/overwritten I guess). A search of my computer for the file names came up empty, even though I was searching with the "search hidden and system files" options enabled!
I tried a number of deleted file restoration softwares but none have identified the desktop files I was missing.
Be so kind as to spare me from the "did you check the power cord" category of "answers", as I am not a complete idiot. The Acrobat Update, or something associated with it has to be at the root of this problem, as the antivirus software I have installed came up empty when I searched the computer for virurses, worms and the likes...
All help on this matter would be appreciated. Needless to say, most of my current work was stored on the desktop...
I am running WindowsXP sp. 3, Acrobat Reader 9.34
With regards

Please ignore the previous unrelated reply - I will deal with it separately.
I must first say that this is a very puzzling problem, and that I have never heard of anything like it. Apart from the missing desktop content, it also puzzles me that you state your Adobe Reader version as 9.34, when the latest Reader version is actually 9.3.2.
Anyway, how to solve it? Can I assume that you do not have a very recent backup, from where you can simply restore all the lost content?
I do not know if your desktop content is really gone (deleted), or if it is somehow just not visible. There are a few things we can try, but I strongly suggest that you make a full backup of your system before you try anything!
Since I have never seen this before, I cannot make any definitive recommendations, but just suggest what I would do if that happened on my computer. Again, not before making a full backup.
Uninstall Adobe Reader.
System Restore to a time before the problem started.
Check the following registry keys, if they have a value 'NoDesktop', and what it is set to
HKCU\Software\Microsoft\Windows\CurrentVersion\policies\Explorer
HKLM\Software\Microsoft\Windows\CurrentVersion\policies\Explorer
If you are on XP Pro, you can use gpedit.msc to check these settings (Configuration | Administrative Templates | Desktop ["Hide and disable all items on the desktop"]).

Using Echosign or Adobe Reader to get signatures

Hello. I would like some feedback on which way to get a document signed in multiple places by multiple parties. I have a secure document that is approximetly 16 pages long that requires signatures by three or more parties. I created an account with EchoSign, because I've read that it's a secure way to transport the document back and forth between the parties who need to sign. I'm just wondering if anyone has any experience using either one of these methods and if you have any advice on which method I should go with. I should add that I've created the document in Adobe Acrobat Pro and I plan to add the electronic document to our web site for the purposes of employee onboarding.
Thank you in advance.
Amanda

The first question is not where the form should be hosted, but what you mean by "digitally signed".
A self-signed ID created in Adobe Acrobat or Adobe Reader is meaningless in terms of proving identity, as anyone can make up any ID - it doesn't even have to have a valid email address. There's no traceability so the signature is not legally admissible, so it's no better than getting them to tick a box or click an 'OK' button.
Verifiable and legally-approved digital IDs are available from commercial vendors, but they cost a fair amount of money and require the application to submit identity documents. Very few people will have one, and nobody will buy one for the fun of it.
EchoSign has no real way to tell who is signing the form, other than the fact the link went to a known email address - the digital certificate on the returned file is actually Adobe's own ID, and it simply proves that someone followed a particular link and drew in their signature on a stated date and time. Because the identity of that person is only traced through their email address, EchoSign will never give you a generic URL to link to the form - in fact you never get to see the encrypted URL sent to your recipients either. You have to enter the email address of each recipient by hand on the EchoSign website, the form can't be hosted on your own server.

Adobe reader DC digital signature

We've been using the sign with certificate function in Adobe reader XI. How do I do that in Adobe reader DC?

You can add a "Verify PDF Signature" operation to your process. This operation throws a "Signature Field Not Signed Exception" when attempting to validate an empty signature field. You could have your process then do something when this exception occurs.
The "Verify PDF Signature" operation requires the name of the signature fields as a property, if you know the signature field object name, then you could hard code this. If not, you can use the "Get Signature Field List" operation to query the form for all of the signature field object names on a form.
If your form has more than one signature field you will need to include a loop in your process to chech each of the signature fields for a signature.
I believe the best method is to prevent the submission of the form unless the signature field was signed.
Regards

Adobe Reader v9 & Digital Signatures

I have some pdf forms, created in Adobe LifeCycle Designer 8, that have digital signature fields. We recently upgraded to Adobe Reader v9. A user completes the form & digitally signs it, then emails it to a supervisor. Since the upgrade to v9 when the recipient views the form they get a message that the digital signature are not verified. Any advice?
We're running on Windows XP.
Thanks in advance.

Why is Adobe Reader X deleting my PDF files when I try to burn to CD?

I am using Adobe Reader X 10.0.1. Within Windows Explorer I mark a pdf file for burning, then click burn at the top of the page. Adobe tells me the file is missing. Then when I check for the file, it is gone! And not in the recycle bin either. I am running Windows 7 64 bit with SP1.

Hi,
The issue is not reproducible at my end.
Please let me know the following details:
1) The "file missing" error message encountered by you is thrown by windows or Adobe?
2) Is issue happening for any specific PDF file or all the PDF files on your system?
3) Is issue happening for the PDF files kept at specific path or all the files on your system?
4) Are you able to burn any other file other than PDF( word document, text file etc.)
5) If the issue is happening for a specific PDF file please let me know the size of the PDF?
Thanks

How do I sign a document in Adobe Reader w/electronic signature?

I'm trying to sign a tax form, its unclear from the Reader doc how to create a signature for use on the document.

Hi Matt,
Starting with the form you want to sign opened in Reader, select the Fill & Sign tool on the right side of the toolbar. This will open the right hand Fill & Sign panel. Next, open (expand) the Fill & Sign Tools pane.
There are three possible scenarios from this point...
The Place Signature tool is disabled (grayed out). This would be because the security setting on the file do not allow for changes.
The Place Signature tool is enabled, but when you select it and get the Place Signature dialog, the only option available is Use a certificate. This is because the document contains an existing signature field and the assumption is the document author requires a secure digital signature as opposed to electronic signature.
The Place Signature tool is enabled,and all of the radio buttons are enable on the Place Signature dialog.
Depending on which of the three scenarios you encounter drive what you can do next. Obviously with scenario 1 there is nothing else to do. With scenario 2 you have to have access to a valid digital ID to create a digital signature. With scenario 3 you have the option of creating either a digital signature using your digital ID, or you can create an electronic signature by placing a mark on the document. That mark can be your typed name, a signature you create with a mouse, or a scanned image of your wet-ink signature.
If you need to create a digital signature, then you need to have access to a digital ID. There are two options for procuring a digital ID; either you can buy one from a trusted Certificate Authority (CA) who will vet your identity, or, you can have Reader generated an untrusted digital ID for free. What you select to do depends on what the second party (you're the first party, the document recipient is the second party, and if a CA is involved they are the third party) requires, or more precisely, what agreement you and other party come to.
I hope this helps get your started.

Adobe Reader not validating signature with three byterange pairs

I have created a PDF with a Digital signature from my program, when opened with Acrobat Reader 10 i see the signature not bieng validated with a message saying, "There are errors in the formatting or information contained in this signature (support information: SigDict /ByteRange value)". My signature's byterange contains three pairs of integers(/ByteRange[0 569 6417 400 6817 1013]) which seems to be causing this problem. PDF-Xchange viewer works fine with the same file. It validates the signature!.. Appreciate any input regarding this.

As described in ETSI TS 102778 (PAdES), the EU standard for PDF Digital
Signatures that has been incorporated into ISO 32000-2, only a single set
of byte ranges (aka two pairs) is permitted.

Adobe Reader XI 11.0.09 Update broke image signatures

I allowed my computer to download and install the latest Adobe Reader XI update, to version 11.0.09. Since doing that, I can no longer sign PDFs. Adobe Reader "forgot" my signature, and prompts me to create a new one, but gives me an error when I try to do so.
The steps I take: I click on Fill & Sign at the upper right. From the Fill & Sign Tools pane, I choose Place Signature. Since Adobe Reader has forgotten my signature, I am prompted by a dialog box that starts with How would you like to create your signature?. I tick the Use an image radio button, then click the Browse... button that appears below it. I choose my signature, which happens to be a BMP file, and click the Open button. Adobe Reader then gives me an error message: This file cannot be used to create a signature. Please select a different file and try again.
I tried converting my BMP file to a TIFF file, but that didn't help.
I need to be able to sign PDF documents again. Is this a bug waiting for a fix, or is there a work-around?
I badly need this feature back again.

Hi, thanks for your prompt responses.
I am a bit perplexed. I take it that, although I have the latest Adobe Reader XI (11.0.10) installed with the latest update 32 and I can open it and use it to read PDF's it is not the correct version for Vista ? As I said when I used the Firefox plug in check, which triggered this whole issue for me, and clicked the red button to update it took me to an Adobe update install page which only offered the 10.1.4 English UK for Windows download (Which you say is actually the correct version for Vista) but this did not complete because it said I have a more functional version already installed which I presume is the 11.0.10 version ?
Do I now need to download the Adobe Reader 'Full Download': Adobe Reader MUI 10.1 - Multiple Languages version 146.67 MB 6/8/2011 or just the Adobe Reader 10.1.4 update, although I may find that I just get the same result as I do using the Firefox update button, it does not complete and I am informed I have a more 'functional version' installed ? Again there are two options for these Updates on the Adobe download page 'All languages' and 'Multi lingual (MUI) installer' and I am not sure what the difference is or , more important, which to use and the Help>About Adobe Reader offers no clue.
Further advice appreciated as I am a bit flummoxed ! Thanks .

Validate signature automatically on Adobe Reader X

Hi!
Adobe Reader 9 auto validates the document signature without doint nothing (only opening the pdf).
With Adobe Reader X the signature appears with a green tick but it says "Signature not verified", and I need to click on it to verify it.
The certificate it's trusted and on the Preferences / Security we have set "Verify Signatures when opening document" (sorry if not it's the exact phrase, I have the spanish version).
Someone could tell me how to say to Adobe Reader X to work as the 9 version did ?
Regards,

Well, I will try to explain a bit better.
Adobe Reader X and 9 shows a top bar with information about the document it's signed and the signature it's ok.
In the body of the document it's one object with information related to the signature as this image:
On Reader 9 it automatically changed to Signature Verified without touching nothing. On Reader X we need to press on this object to verify the signature another time and to change this object text to Signature Verified.
Someone knows how to work as Reader 9 did ?
Thanks for reading.

Adobe Reader and Photoshop extensions default to preview in Mountain Lion.

My pdf files and all my images that I have designated to Adobe Reader and Photoshop in the "Get Info" window of these files... continually Default to Preview after a few days. This must stop... I never had this issue in Snow Leopard or Lion! Yes... I do hit the "Change All" button each time. Apple and Adobe seem to be at WAR over Preview, and we are payng the price!

For Adobe Reader, try deleting the application, downloading it and reinstalling. I just did this and the first time I opened it, I was asked if I wanted to make it the default.

Adobe Reader X (10.1.1) Invalid plugin detected. Adobe Reader will quit.

This is the second time this has happen.
My system consists of the following:
PC running Windows 7 w/64bit
When I try to open a .pdf Iget a pop-up within 10 seconds say Invalid plugin detected. Adobe Reader will quit.
I paid the $39.00 from tech support to get this fixed in Aug. 2011 and now it's back.
I have gone through all the Adobe hoops and nothing has worked.

Hi,
Do you have any 3rd party plugin installed for Adobe Reader? If not, close all running instances of Adobe Reader and delete the entire folder at: C:\program Files\Adobe\Reader 10.0\Reader\plug_ins.
Now goto Control Panel > Programs and Features. Locate the entry for Adobe Reader X and chose to repair the installation.
If you do have a 3rd party plugin installed, try uninstalling them and see if the issue is related to the same. If it works, do let me know which plugins were causing the issue so that I can have a look.
Hopefully, this should fix things.
Thanks

Appending new pages to signed documents now makes Acrobat 9 and Reader 9 mark signature as invalid

Hello!
I have developed a service that appends additional pages to existing PDF documents. Some of the documents the service works on happen to be signed. As the service appends the pages using incremental updates, the signed contents are left untouched. This makes Acrobat 8 and Reader 8 display the signature state as "valid with subsequent changes" which is ok and no one complains about.
Now along come Acrobat 9 and Reader 9, and all of a sudden the signature state is "invalid" which my users do complain about. Telling them that inspecting the signature state details they can see that the signed content still is untouched and the actual change is recognized to be some appended pages, doesn't help either as they in turn forward the documents to their customers who don't accept the documents if the Adobe Reader sais the signatures are invalid.
Does anyone know a way new pages can be added to a signed document without having the new Adobe program versions choke on them?
Even a hint that involves adding some flag to the original unsigned document or the signature itself would help as the users in question can tweak those processes. Due to the nature of the workflow, though, signing unfortunately must happen before my service can add the new pages.
Best regards, Mikel.
By the way, the signatures in question are regular approval signatures, nothing fancy, especially not certifying signatures (which indeed can forbid any changes or at least any changes but some form fill-ins and annotations)...

Hi Fritz,
In the interest of full disclosure, I got the answer to the problem from one of my distinguished colleagues, I'm just the messenger in this case.
The problem is that the form adds some items to the Arzneispezialität / Zusatztext combobox which are there during signing but the form doesn’t remember that it did this on the next form open.
Since this field is included in the MDP+ signature and the field has changed in the re-opened version vs. the signed version, the MDP+ signature becomes invalid.
XFA has a feature that remembers these kinds of things for you but it is turned it OFF. Please open the attached screen shot to see the control in question.
So, you can either (1) turn this feature ON (Automatically), or (2) write some script to clear the combobox items prior to signing or (3) write some script to repopulate the combobox items on the subsequent open to match the items that were there during signing.

Opening a file from the Cloud of Adobe Reader - Ipad

Hi,
I have got a serious trouble with my Ipad. It's been about 3, maybe 4 days that I can't open my files from the cloud of Acrobat.com if it hasn't been open recently, thus not in the docoument.
When I try to open a file, I click on it, and then, it do not open, just stay blocked on "Opening... X Mo." without never progressing.
I thought it was maybe the internet connection. But the Cloud of Pages, Numbers and Keynote works perfectly.
Then, I did some manipulations on Adobe Reader : I deleted it, then downloaded it. All the files are in it, but I can't open them. I 've checked the version of Adobe reader and it's the latest one. I've checked the version of My Ipad, and it's the lastest one too. I even turned off my Ipad, then turned it on. Nothing.
So, I thought it was maybe the files itself. But I can open them on the cloud of my computer.
Ps. About subscriptions, I bought the Pack (about 79€ a year).
Sarah
Sorry for my english, I'm french
Hope you'll understand what I'm saying.

Hello everyone !
I backed up my Ipad, then restored it and... It works
Hope It will help some of you. I was soooo deperate and then, I can get back to work
