Fix Windows Installer Error When Opening Adobe Acrobat Reader DC
Question details
The user is encountering a recurring Windows Installer error stating that the AcroRead.msi package is unavailable on a network resource when trying to launch the software.
- Product
- Adobe Acrobat Reader DC
- Device & OS
- Windows
- Scenario
- Opening the application directly or attempting to view a PDF file on the computer.
- Observed behavior
- The application fails to open, repeatedly launches the Windows Installer process, and displays an 'AcroRead.msi unavailable' error message.
Ensure you have administrative privileges on your Windows computer, as using specialized cleaner tools and reinstalling software requires admin access. Close any background applications and save your current work.
Perform a Clean Reinstallation Using Acrobat Cleaner Tool
Using the official Adobe cleaner tool ensures all corrupted installation files and broken registry keys are completely removed before attempting a fresh installation.
A standard uninstallation via the Windows Control Panel often leaves behind broken registry keys or temporary files that continue to trigger the Windows Installer loop. Using a dedicated cleaner tool resolves this root cause.
Navigate to the official Adobe Labs website and download the Adobe Acrobat Cleaner Tool specifically designed for Windows.
Launch the downloaded tool, accept the terms, and follow the on-screen prompts to completely remove Adobe Acrobat Reader DC from your system.
Once the tool finishes processing, restart your Windows PC to clear any residual temporary files and halt any stalled installer processes.
Visit the official Adobe Acrobat Reader download page and download the most recent version of the installer directly to your local hard drive.
Run the newly downloaded installer from your local drive (such as your C: drive). Do not run it from a shared network folder, as this can recreate the network resource error.
Repair Adobe Acrobat Reader DC via Windows Settings
If the application's core files are only partially corrupted, the built-in Windows app repair feature might restore the missing .msi file reference without a full uninstallation.
Open and Edit PDFs Instantly with WPS Office
If Acrobat Reader DC continues to display persistent installer errors, you can easily open, view, and edit your PDF documents using WPS Office. Its built-in, lightweight PDF reader completely bypasses Windows Installer loop issues while providing advanced features.
- 1. Download WPS Office: Download and install WPS Office for free from the official website.
- 2. Launch the PDF Tool: Open the WPS Office application and click on the 'PDF' tab located on the main home screen.
- 3. Open Your Document: Click the 'Open' button and browse your computer to select the PDF file you were previously unable to view.
- 4. Set as Default Reader: To prevent future Adobe errors, right-click any PDF file on your PC, select 'Open with', click 'Choose another app', select WPS Office, and check the box to always use this app.
Frequently Asked Questions
Why does Acrobat Reader DC keep asking for the AcroRead.msi file?
This issue occurs when the original installation source files have been moved, deleted, or are located on a disconnected network drive. When Acrobat attempts a background update or self-repair, it fails because it cannot locate the required installer package.
Can I fix the AcroRead.msi error without completely reinstalling the app?
Sometimes running the 'Windows Program Install and Uninstall troubleshooter' provided by Microsoft can resolve broken registry keys. However, performing a clean removal using the Adobe Cleaner Tool and reinstalling is generally the most reliable long-term solution.
Where can I safely find the official Adobe Acrobat Cleaner Tool?
The official Adobe Acrobat Cleaner Tool is available for free download directly from the Adobe Labs or Adobe Help websites. Always avoid downloading such system tools from third-party hosting sites to prevent malware.
How do I temporarily stop the Windows Installer dialog from popping up constantly?
You can force-close the loop by opening the Windows Task Manager (press Ctrl + Shift + Esc), locating the 'Windows Installer' or 'msiexec.exe' process in the list, and clicking 'End task'. This will stop the pop-up so you can proceed to uninstall the software.
