Problemas com win11 e adobe v26.0001, o programa simplesmente trava na hora de abrir a janela para assinatura digital ou quando é selecionado para assinatura com certificado digital, não aparece os menus do lado esquerdo ao selecionar alguma das opções, as notificações não aparecem, isso aconteceu recentemente, desistalei a ultima atualização do Windows e refiz a instalação do adobe, mais sem sucesso, problema aconteceu recentemente pois uso o assinador com frequencia.

    Olá, obrigado pelo retorno, os passos 4 e 3 foram executados sem sucesso, uso uma chave do tipo A3 que fica armazenada no computador.

    Já desinstalei as ultimas atualizações win11 25H2, limpei pasta TEMP

    Usei o Adobe Tools, refiz a instalação

    Usando a interface antiga

    Acrobat 64, 26.001.21789

    Sempre usei o assinador Adobe, porem agora parece que há um erro quando seleciono a área de assinatura e ele vai acessar a assinatura, por outro assinador eu que instalei eu consigo realizar normalmente

    EM editar, configurações IDs digitais ela aparece como válida.

    Hi ​@Brave_personality6131  Thanks for the details, that helps narrow it down.

    Since your other signer works fine with the same A3 token and the Digital ID shows as valid in Acrobat, that suggests the certificate and token itself are fine, and the problem more likely sits in Acrobat's signature cache files or a conflict with the token middleware after the Windows 11 25H2 update.

    A few specific things to try: First, delete Acrobat's signature cache files. Corrupted cache files are a common cause of crashes right at this point in the signing process:

    Press Windows + R, type %appdata%, and hit Enter. This should open C:\Users\[YourUsername]\AppData\Roaming

    Navigate From that Roaming folder, manually click into:

    • Adobe
    • then Acrobat
    • then DC
    • then look for Security

    Delete these files: acrobat_fss_signature_initials acrobat_fss_signature_initialsi acrobat_fss_signature_initialsk Then try signing again, recreating the signature if needed.

    Second, reinstall the middleware/driver for your A3 token (the token manufacturer's software, not Acrobat itself). Sometimes the Windows 25H2 update affects how the token middleware integrates with the Windows CSP.

    Third, try running Acrobat as Administrator once, just to check if that resolves it, though it shouldn't be necessary for daily use.

    Let us know how it goes.

    ​Hi @Brave_personality6131 ,

    Hope you are doing well, and thanks for reaching out. We are sorry for the trouble you are experiencing.

    This freeze-on-signing pattern usually comes down to one of a few specific things, so a bit more detail would help:

    • What's the exact app and version you are using? (Acrobat Reader or Acrobat Pro, check Help > About for the full number, since "v26.0001" is a bit short to go on)

    • Are you signing with a physical certificate/smart card or USB token (like a government ID card reader), or a digital ID you created yourself in Acrobat?

    • Does this happen with every PDF, or only some?

    A few things worth trying while we wait to hear back:

    1. Turn off the modern signing interface. Go to Edit > Preferences > Signatures > Creation & Appearance > click More, and uncheck "Use modern user interface for signing." and reboot the application once, and check.

    2. If you're using a smart card, USB token, or a certificate tied to a government/bank signing service, check whether that software has its own update; those drivers are a common cause of exactly this kind of freeze, separate from Acrobat itself.

    3. Repair the installation rather than just reinstalling. Go to Help > Repair Installation and reboot the application once, and check if that helps.

    4. If repair doesn't help, do a clean removal first. Remove the application using the Acrobat cleaner tool https://adobe.ly/4fZhh9O, reboot the computer, and reinstall the application using the direct link https://adobe.ly/4qh8V0D

    Let us know how it goes.
