Thank you for posting your question in the Microsoft Q&A forum
From your description, this looks like Microsoft Store itself has become corrupted, not just Lenovo Vantage. Once the Store breaks, all apps depending on it fail to download or update, which matches your situation (“Retry” button, nothing installs, even other apps fail).
Here are a few steps you can try:
- Force Clear the Broken Files
- Open PowerShell as Admin: Right-click the Start button and select Terminal (Admin) or Windows PowerShell (Admin).
- Run the following commands one by one (copy and paste, then press Enter):
- This command removes the Vantage package completely: Get-AppxPackage -AllUsers E046963* | Remove-AppxPackage -AllUsers
- This command clears the Microsoft Store's internal cache: wsreset.exe (A blank black window will appear; wait for it to close and the Store to open automatically.)
- Repair the Microsoft Store
- Open PowerShell (Admin) again.
- Paste this command to re-register the Store app: Get-AppXPackage WindowsStore -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
- Restart one more time.
- Fresh Install
- Open the Microsoft Store.
- Search for Lenovo Vantage and try the download again.
- Once it opens, it may ask to download "Additional Services"click Yes/Download. This will restore that "Vantage Services" app you were looking for.
Hopefully it will help work with your issue and if you have any other questions or need further assistance, feel free to ask.
