This problem is most often caused by limited permissions on the WindowsApps folder or problems with App execution aliases, but it can also come from broken or missing Store cache folders. Now that you know the possible causes, here’s a list of methods that have helped users fix this Microsoft Store error:

1. Update your Windows

First, make sure Windows is up to date. An outdated system can cause the “can’t install apps” error. This applies to both Windows 10 and Windows 11. Go to Windows Update and check for updates. If there are any, install them. You’ll find Windows Update in Settings.

2. Update Microsoft Store

Next, make sure the Microsoft Store app itself is up to date. If the Store is outdated, app installs can fail. Sometimes automatic updates don’t apply right away. Open the Microsoft Store and go to Library to check for updates. If updates are found, they’ll install.

3. Repair or Reset Microsoft Store

You can also repair or reset the Microsoft Store. Many users fixed installation issues this way. Repairing or resetting replaces any corrupted files that might stop the Store from working. This is often enough to get it back on track. Go to Windows Settings and open the Advanced options for Microsoft Store. Try Repair first; if that doesn’t help, use Reset.

4. Run the Windows Store Apps troubleshooter 

Running the Windows Store Apps troubleshooter has helped many users fix install issues. It can find common problems and recommend fixes automatically. Note: This works on both Windows 10 and Windows 11, but the steps to get there are a bit different. If you’re using Windows 10 and need help, search online for the specific steps for your version.

5. Check the Microsoft Store Install Service

Make sure the Microsoft Store Install Service is running. If this service is disabled, the Store can’t install apps. This service provides the background support the Store needs, so it must be enabled. Open the Services app, confirm the service is running, and restart it to be sure.

6. Reinstall the Microsoft Store 

As a last step, reinstall the Microsoft Store. The easiest way is with PowerShell. Open PowerShell as an administrator and run a command that reinstalls Microsoft Store.
