This error may occur if you are not currently connected to the Internet or if you have tried to install the product without an active Internet connection.The first time sign pro PDF is used you must be connected to the internet to obtain a license.Once you have acquired a license you can use sign pro PDF offline for up to 14 days. This 14 day period will be refreshed every time you reconnect and get a new license.
Another possibility is that your trial 30-day licence has expired and you need to upgrade to a paid edition.If this is the case go to the Wacom marketplace and you will probably see the screenshot below indicating that you need to start paying.
If the specified keyword is not present in the document, then it will not be possible to sign.However, you can change your settings by navigating to Options -> Signature Area, and selecting the radio button against "Position signature with mouse".
Previous attempts to make the pen work with sign pro PDF may have included new registry settings. They should be removed using Windows Registry Editor regedit.
The following is a complete list of expected values created by the sign pro PDF installer. Any other values will need to be removed (or renamed):
In the event of a handwritten signature being questioned it is necessary to compare it against a set of samples that are known to be genuine.
This requirement applies equally to ink-on-paper signatures and to electronic handwritten signatures.
A large number of genuine samples should be used because signatures are always variable, and it is important to take this natural inconsistency into account.
The questioned signature can then be scrutinized to detect any features that are inconsistent with the normal signatures.
To the user the signatures embedded in the PDF documents look like nothing more than static images, and the visual appearance alone is inadequate for the purposes of forensic assessment.
However, the full FSS data can be extracted using forensic tools designed for this purpose.
The main application used is Wacom SignatureScope which allows the full depth of biometric and forensic data to be examined and compared.
SignatureScope was designed in cooperation with Forensic Document Examiners and is intended for use in legal proceedings.
If you lose the certificate it does not matter because it is not necessary to ensure the validity of the document.
Once the public key has been attached to the document you don't need the private key anymore.
The "Signing Certificate" (also known as a "Digital Certificate" or "Digital Signature") is used to prevent the signed document from being modified.For more information on Signing Certificates please see also -is-code-signing-certificate/
If you have installed both sign pro PDF and the Signature SDK please note that in these circumstances sign pro PDF may encounter problems when starting up.
It is important to install these two products in the correct order:
We recently upgraded to Acrobat DC. We have documents that have been digitally signed. Now when someone else opens them it says "The validity of the document certification is UNKNOWN. The author could not be verified." I've read up as much as I could (didn't know anything about them except how to sign a doc with one) and I've checked several things and can't find the problem. When I go to the certificate viewer it shows that we have a Certificate Authority. I read on another post that the latest Acrobat/Reader version enforce "Extended Key Usage" (EKU) attribute in the signing certificate. I checked that out and the OID (not sure what that stands for) that permit signing has five things: server authentication, client authentication, code signing, email protection and TimeStamping. It says in the Revoation tab "The selected certificate does not chain up to a certificate designated as a trusted anchor (see the Trust Tab for details). The result is that revocation checks were not performed on this certificate." It seems that I could "Add to Trusted Certificates" but we've never had to do that before, why now? Not to mention it advises me that I shouldn't do that. Please help. Thanks! Let me know if you need anything other information to trouble shoot.
Make sure that you trust the root of the certificate chain (only if you really-really trust it!). Right-click on the signature (either the signature field or in the Signature Panel on the left), select "Show Signature Properties.." in the drop-down list and then "Show Signer's Certificate". You'll see the trust chain in the left-hand panel of the "Certificate Viewer" dialog (if the signing certificate is self-signed it will be the only one in the chain). Select certificate in the chain that you trust (if you trust any) and click the "Trust" button on top of teh right-hand part. Then select the trust level and click "Add to Trusted Identities" button. Be extra careful to trust self-signed signing certificates.
Please help me also. I purchased this certificate through identrust and it is valid and I trust my signature. But the signature should be trusted on any computer that it is sent to. I had to import this certificate from my laptop because I installed it there initially but I don't use that laptop often. So now on my desktop its showing this error and my clients are questioning why its giving this error. I tried to trust it on my own computer but then it has a revocation error. saying it was not performed because it doesn't chain up to a trusted anchor. What does this mean in laymans terms? Please explain it to me like I'm a child without the confusing tech language. If its an error I can't fix because it was imported let me know. If I can fix this so that my clients see the green check mark, please help. Thanks!
Bottom line: you need to get a key that is trusted by Adobe in its Adobe Approved Trust List. While Identrust is on the AATL, you need to buy the correct digital certificate. The cheaper certificates will not automatically validate on Adobe. You will need to buy the digital certificate in the second Identrust link that I've provided.
Under Security Settings\Digital IDs\Window Digital IDs I have an ID that appears to be invalid and states "The selected certificate has errors: Not time valid" along with stating that the certificate is not trusted.When I try to remove the ID I get this message "Removing a digital ID is only permitted if the ID was created by Adobe Reader or Arcobat version 8.0 or later".
My signature used to work before my IT rolled over my office into a new Domain and changed Admin rights not sure if this caused error in first place but they where unable to get my signature working again.
In all probability the digital ID has expired. There is an expiration date listed in the Security Settings dialog, what does it say? If the digital ID has indeed expired, and you would like to remove it from the Windows Certificate Store you need to do it through a Windows interface, not through Acrobat. Like many things, there are more then one way to go about this, but the simplest is to start Internet Explorer. From Internet Explorer select the Tools menu or button, and then Internet Optio

Here is where you'll see the digital IDs loaded into the Windows Certificate Store. You can highlight the expired ID that you would like to delete and click the Remove button, BUT FIRST, I strongly suggest that you Export the ID to a file in case you ever need to get back to it for some reason. Think of this as escrowing or archiving the digital ID just in case. Once you've saved the digital ID to a file, then you can remove it knowing that you could resurrect it at some time in the future.
I was able to delete the invalid Digital ID using your instructions. I had to create a completely new Digital ID even though I already had a valid one. But once I created a new Digitial ID and changed the Usage Options in Advanced\Security Settings\Windows Digital IDs from the old one to the new on it worked.
