How to Fix Cannot Sign In to Install the Adobe Acrobat DC Free Trial
Product
Adobe Acrobat DC
Device & OS
not provided
Scenario
Installing the Adobe Acrobat DC desktop application to begin a free trial.

Before you start

Ensure you have the login credentials for both your Adobe ID and your computer's local administrator account, as both may be required during installation.

Solution 1Recommended

Enter Your Computer Administrator Password

The installer is likely requesting your local computer's administrator password to authorize the installation, not your Adobe account password.

A common point of confusion during software installation is the system permission prompt. Operating systems require local administrative approval to write application files to the hard drive. This prompt is generated by your OS (Windows or macOS), not Adobe, meaning your Adobe ID password will not work here.

1
Review the login prompt

Look carefully at the credentials box that appeared. If it mentions 'System Administrator', shows your computer's local username, or displays a system shield/lock icon, it is an OS-level prompt.

2
Enter the local system password

Type the password you use to log into your computer or laptop when you first turn it on. Click 'OK' or 'Allow' to grant permission.

3
Wait for installation to complete

Allow the Acrobat DC installer to finish copying files. Do not close the window until the progress bar reaches 100%.

4
Sign in with your Adobe ID

Once the application launches for the first time, an Adobe-branded sign-in window will appear. Enter your Adobe ID email and password here to activate your free trial.

Enter Your Computer Administrator Password
Administrator Privileges Required: If you are on a company-managed computer, you may not have the local administrator password. You will need to contact your IT department to authorize the installation.

Frequently Asked Questions

Why is the installer rejecting my newly reset Adobe password?

The installer is likely prompting for your computer's administrator password to grant installation permissions to the system, rather than your Adobe account password. Try entering your Mac or Windows login password instead.

Do I need administrator rights to install the Acrobat DC trial?

Yes, installing desktop applications like Adobe Acrobat DC requires local administrator privileges to make necessary system changes and write application files to your hard drive.

How do I know if my Adobe free trial is actually active?

You can verify your trial status by logging into the Adobe website on your web browser. Under your account management dashboard, check the 'Plans' section to ensure the Acrobat DC trial is currently active and linked to your email.
