Select the " Trust" tab in the "Certificate Viewer" window, where you can now see that the certificate is not trusted.In the next window, you have the option to add the certificate to Adobe Reader's list of trusted certificates - that is, if this is a valid certificate. Press "Show Signer's Certificate." after which you can see information about the certificate.When you have pressed "Show signature Properties." a pop-up will appear, in the pop-up you must access the signing certificate Right-click with your mouse on the signature that reports an error.Tap on "Signature Panel" if it is not already open.If the error "At least one signature has problems" is still visible, it requires us to go into the settings for a signature, by browsing the certificate. however, I would recommend that you take a look here, to see what you can so in the future If the signatures are successfully validated, Adobe Reader displays that the documents are signed and all signatures are valid. ![]() Make the certificate a trusted identity in your Adobe reader We will now go through other possible issues, that aren't related to the design of the file. The document is now saved as a PDF file (again) this time however, any elements that would not have been shown properly by Adobe, (And changed after signing!) are changed to adobe standards.Select the printer: Microsoft print to PDF.Open the original Non-signed document, and click File in upper right hand corner. ![]() The following fix does not alter the document in any way that simply signing the document usually wouldn't, but it does ensure that when the document is signed, it will verify the signature correctly. Note - this report code and description, does not always show, even if this issue is the case. If the PDF was made in an older version of Adobe Acrobat, or some other form of file editing program, Adobe may have an issue validating the signature, as the document is altered once Adobe opens it, with the signature.Ĭertain Fonts, colors or images may cause this issue. We will now guide you through how to "fix" the document, in order to avoid this issue with future signings. These can be design elements or javascript that cause images or fonts to change when the document is opened in Adobe. The certificate is not an LTV (Long Term Validation) document - This requires a time stamp for the signature.Ī very common reason for this problem is that the original PDF (Before the Signature) contains design elements that are not supported by Adobe.The signer's identity is not captured and embedded in the document.The certificate used to sign is not an AATL/EUTL certificate.I'm running the latest version of Acrobat DC 5.0, 2.4ghz 8 core i9 with 32GB RAM, MacOS 12.If you experience this error, it can therefore mean the following: ![]() Are there some settings I can change so it doesn't feel like I'm using the app on a Macintosh Classic?īeyond that, all the endless bloated license management software/processes Adobe forces on to your system, installing/paying for Adobe is really a tough pill to swallow. Is it just me or is Acrobat honestly some kind of disaster in desperate need of a rewrite from the ground up? I find myself using Preview for almost everything. I cannot fathom why something as simple as displaying/editing PDFs could be so slow and unbearable, it's like they've ported the codebase from Windows 95 to run on Power PC, then back to Intel. Scrolling pages is painfully laggy/unnatural, I frequently encounter endless "Preparing document." dialogues which render page editing impossible, frequent crashes etc. On maxed out i9 mac systems with 32GB RAM, it is so painstakingly slow, buggy and bloated. I've stopped myself from posting a rant about how much I hate Acrobat at least seven times, but as someone who has paid for Adobe software for over a decade I simply cannot bear how frustrating it is to use Acrobat.
