I also have an issue with the digital signature. I have used the same signature for my business since 2003. Now all of sudden it doesn't sign the documents as it did beforehand, I spent 7 hrs last night trying to sort it out even with technical support. I'm demanding my monies to be return. not because it does do want it to do, because I sick to death of software companies like Adobe who promote the product but fail to inform people what changes have applied to the new versions, plus since I down loaded the upgrade my internet explorer now work extremely slow. I feed up with software companies using their customers as guinea pigs whilst charging the customer for the privilege. After spending nearly 2 hrs with customer technical support until 1.35 am in the morning a losing valuable time & monies they want me to continue to contact them to sort the issue out. Not going to happen. Adobe can get off its backside and fix the issue. I also see that securing the document also has different features in it. You can secure the document but it still allows others to alter it, what joke.
All adobe are interested in money grabbing schemes they have become a big disappointment for such a powerful software program. I also doubt they give a toss either since they have haven't answered your question either. I will be looking to see if the ACCC can take the issue on today.
one very annoyed customer
It'd be nice if instead of venting on this forum which is mostly answered by technical people (many non-Adobe) who have next to none influence on getting your money back (or in addition to venting) you've also provided specifics of what's going on.
First, learn and use correct terminology. You are not "using the same signature". You are using the same signing certificate to sign many signatures. Please, provide detailed description of your workflow and experience, indicating what's going on wrong. Do you get any alerts, UI indicators, etc.?
One possibility is that your certificate has expired. Each digital certificate has a validity period and cannot be used outside its range. Are you using a self-signed certificate that you created in Acrobat or have you procured it from a Certificate Authority (CA)? Have you installed your certificate in the Acrobat store (Digital IDs) or Windows store (if you're on Windows) or keychain (if you're on Mac)?
Which product (Acrobat/Reader) do you use? Which version, including minor? Which platform (Mac/Windows), which OS/version/SP?
Examine the store in which your signing certificate is installed and examine your certificate. My bet is that it has expired. If this is the case you need to procure a new signing certificate (either create a new self-signed one or procure it from a CA).
The better way to do get your signatures validated is to use Acrobat facilities not Windows facilities. When you have a signature that is not trusted, right-click on the signature, select "Show Signature Properties" and then "Show Signer's certificate". In the Certificate Viewer that comes up. select the root (top) certificate in the left pane and then click on the Trust button in the right pane. Then click on "Add to Trusted Identities". When you do that be sure that you know who the root is and that you really trust it.
First a foremost I wasn't venting anything. The Adobe signatures has changed, I spent many hours after that post with technical support from Adobe, they couldn't fix it, I have had experienced managers on the phone to me for over a week, In the end I been given a full refund, I have never used windows signature. I also have made it clear if adobe get it right I will upgrade to Adobe Acrobat DC again. Adobe need to fix the issue and not at the expense time of it customers.
