The Windows installer is a key component responsible for the installation, modification, and uninstallation of software products. Consequently, any issues with the Windows installer component will prevent the installation or uninstallation of applications. Other potential causes of error 0x8A150049 include corrupted Microsoft Store files and cache. Having discussed the causes, let’s proceed to the solutions.
1. Restart the Windows installer service
Considering that problems with the Windows installer are among the primary causes, it is advisable to begin by troubleshooting this component. Restarting the Windows installer service may resolve the issue, allowing you to install the Microsoft Store app without encountering the error message.
2. Reregister the Windows installer service
Reregistering the Windows installer service can be an effective troubleshooting step for error 0x8A150049.
3. Ensure TLS 1.2 and TLS 1.3 are enabled
Transport Layer Security (TLS) is a protocol designed to secure communications between a client and a server. Enabling TLS 1.2 and TLS 1.3, which are the more recent versions of the TLS protocol, has resolved many Microsoft Store error codes.
4. Reset the Microsoft Store cache
Occasionally, cache data can become corrupted, which may interfere with app installation. This is a common issue with the Microsoft Store. If this is the case, simply resetting the Microsoft Store can clear the cache and potentially resolve the problem.
5. Reinstall Microsoft Store
If none of the above methods work, you may need to reinstall the Microsoft Store, as file corruption within the Store may be preventing proper installation of apps. Unlike third-party apps, the Microsoft Store cannot be uninstalled in the traditional manner. You will need to use Windows PowerShell and specific commands to reinstall the Microsoft Store. If reinstalling the Microsoft Store does not work, it is possible that the Windows installer component is damaged, which is why you cannot install apps from the Microsoft Store. To address this problem, consider resetting your Windows without losing data, or use a system restore utility if you have previously created a restore point.
