Fix Adobe Acrobat Reader Installation Requesting Wrong Username and Password
Question details
The user is trying to install Adobe Acrobat Reader, but the installer rejects the entered username and password, halting the installation process.

- Product
- Adobe Acrobat Reader
- Device & OS
- Windows and macOS
- Scenario
- Installing the Adobe Acrobat Reader software on a local computer.
- Observed behavior
- The installation prompt rejects the user's Adobe account credentials because it is actually requesting the computer's local operating system administrator credentials.
Ensure you know the local administrator username and password for your computer before beginning the software installation process.
Enter Local System Administrator Credentials
Resolve the installation error by providing your computer's local admin username and password instead of your Adobe ID details.
During software installation, both Windows and macOS use built-in security features (like User Account Control or the macOS Installer) that require local administrative privileges to write system files. This authorization prompt is generated by your operating system to protect your device, not by Adobe.
Look at the prompt window carefully. If it mentions 'User Account Control' on Windows or 'Installer is trying to install new software' on a Mac, it requires local system credentials.
Enter the username of the administrator account you use to log into your computer. On a Mac, this is usually your local user profile name.
Type the exact password you use to unlock your computer screen upon startup. Do not enter your Adobe account password here.
Click 'Yes', 'OK', or 'Install Software' to authenticate the credentials and allow the Adobe Acrobat Reader installation to proceed.

Frequently Asked Questions
Why does the installer reject my correct Adobe password?
The prompt you see during installation is generated by your computer's operating system, not Adobe. It requires your local computer's login password to authorize system changes, so your Adobe ID password will be rejected as incorrect.
How do I know if the prompt is for my OS or my Adobe ID?
OS credential prompts typically appear in a standard system dialog box (like Windows User Account Control or macOS system dialog) and usually mention making changes to your device. Conversely, an Adobe ID prompt will feature Adobe's branding and explicitly ask you to 'Sign In' to your account.
Can I install Adobe Acrobat Reader without administrator privileges?
Generally, no. Installing software that modifies system directories requires administrative rights on both Windows and Mac computers. If you do not have these rights, you must contact your system administrator or IT department for assistance.
