Kindly assist me to resolve this issue.

Answer 1

Hi Oluwabukola,

Error 0x80073D28 ("ERROR_PACKAGED_SERVICE_REQUIRES_ADMIN_PRIVILEGES") means the package installation failed because administrator privileges are required.

• Are you logged into an admin account? To verify that, open Command Prompt and run the command net user %username% and press Enter. Post the output of that command in your next reply.
• If you're trying to install the app from the Microsoft Store, please mention the link or a screenshot of the app page so that I can try to repro the issue on my system.

Answer 2

The error dialog shows that the Claude installer is failing when trying to add an MSIX/Appx package (AddPackage failed with HRESULT 0x80073D28). This is a Windows app installation issue.

On Windows 10/11, MSIX/Appx installation can fail if sideloading is not allowed, required framework packages (like VCLibs) are missing, or the package/certificate is not trusted. Use the following steps to troubleshoot:

1. Ensure sideloading / app installation prerequisites
   • On Windows 10, the device must allow sideloading or Developer Mode for some Appx/MSIX installs. See the prerequisites in Troubleshoot installation issues with the App Installer file and make sure the device meets them (trusted certificate, supported Windows version, and sideloading enabled where required).
2. Check that required framework packages are installed
   • Some MSIX packages depend on Microsoft Visual C++ runtime packages (VCLibs). If these are missing, installation can fail.
   • The Basic troubleshooting for Windows App article shows the pattern for manually installing dependencies:
     1. Open PowerShell as Administrator.
     2. Navigate to the folder that contains the dependency .appx files (for example, Microsoft.VCLibs.140.00_...appx and Microsoft.VCLibs.140.00.UWPDesktop_...appx).
     3. Install them with:

                Add-AppxPackage .\Microsoft.VCLibs.140.00_14_0.33519.0_Universal_X64.appx
                Add-AppxPackage .\Microsoft.VCLibs.140.00.UWPDesktop_14.0.33728.0_Universal_X64.appx
        

   • After installing the required VCLibs packages, rerun the Claude installer.
3. Verify the package’s certificate is trusted
   • For sideloaded MSIX/Appx packages, the signing certificate must be trusted by the device. If the installer includes a certificate, install it into the Trusted People/Trusted Publishers store, then retry the installation.
4. Re-download and reinstall
   • If the package or its dependencies were partially installed or corrupted, re-download the Claude installer, then run it again after completing the steps above.

If the error persists after these steps, use the log file that Claude Setup opens in Explorer and share it with Claude’s support, as the dialog suggests, so they can identify any missing dependency or policy blocking the install.
