Adobe Acrobat Pro 2020 - asking to sign in loop

  • September 9, 2025

Hello everyone,

 

we bought Adobe Acrobat Pro 2020 licence with serial key. I have created the account, registered serial key, downloaded the multilingual package and installed it with serial key on our Windows Server 2022.

When I launched the Acrobat 1st time, it asked to sing in, so I did with the account that has the serial key registered, and everything worked just fine - but UI is in English. So I switched Language to my native, Czech.

And here the problem starts. Acrobat wants me to sing in - again. When I do with same account as before, it asks me for the serial key, so I enter the key, then I have to sign in again and so on...

 

I have found few posts here mentioning "Sign in" loop, but my problem isn't related to "Save as" feature, as I can't get into the Acrobat through the "Sign in" window, when Czech language set is active.

 

I tried to uninstall the Acrobat, use the Acrobat Cleaner, reinstall Acrobat, use the Customization Wizard to disable online features. None of this works. When I start Acrobat in English, its working fine, when in Czech (via CTRL launch), I get the "Sing in - Enter serial" loop.

 

Can anyone help?

    Hello kglad!

    I have figured it out.

    The license was purchased as used software from software broker - which I didn't know.

    It was delivered by one of our IS supplier - so I thought it was a new license.

    The serial key is obviously locked on language, which Adobe is known to do.

     

    Thank you for your time.

    Hello I am also expierencing this issue with one of our clients. They purchased these licenses before they onboarded with us. They bought these licenses through tech soup. I asked my client if they activated these through an adobe account. this has not be activated on my specfic users adobe account.  I tried to register the product and was not able to as it said it was registered already. Any suggestions I tried to get ahold of support but do not have an plan with Adobe for support. I am looking for some guidance on this.

      it has to be activated to work beyond the 30 day trial period.

        you're welcome.  but beware, if it was recently purchased, it will probably be revoked.
