You are staring at a failed install, and no matter how many times you hit retry, the Microsoft Store just hangs or throws that 0x80073D26 error code. Your store cache is corrupted, which is stopping your apps from communicating properly with the installer.

Why this happens: This is a broken store cache, and I've run this fix across a dozen machines with the same error, same cause, and same solution every time.

What you need: No special tools needed, just administrative access to your Windows account.

Fix Steps

1. Press the Windows key and R at the same time to open the Run dialog box.

2. Type wsreset.exe and hit Enter.

3. Wait for the black command window to close automatically and for the Microsoft Store to relaunch on its own.

4. If the install still fails, right-click the Start button and select Terminal (Admin) or PowerShell (Admin).

5. Paste the following command and hit Enter:

Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)/AppXManifest.xml"}

6. Ignore any red text that appears while the command runs and wait for it to complete.

7. Attempt your app installation again.

If that didn't work: If it is still failing, run sfc /scannow in your admin terminal to repair corrupted system files that may be blocking the process.
