Diagnosis
This specific error in the Microsoft Store—where the "Get" or "Install" button is greyed out or triggers a "you can't install apps" notification—is typically caused by a conflict between the Windows Store's regional verification system and your current network configuration. The Microsoft Store validates your IP address against your account's region settings to ensure the software is licensed for your territory. When a Virtual Private Network (VPN) or a strict corporate proxy is active, it masks your true IP or routes traffic through a server in a different country, causing the Store to block the installation of regional-specific drivers like those for the HP OfficeJet Pro 9015e. Beyond VPNs, this issue often stems from a corrupted Microsoft Store cache or a "Limited" user account profile. If you are using a work-managed laptop, your IT department may have implemented a Group Policy Object (GPO) that restricts the installation of third-party applications from the Store. You can confirm this by attempting to download a lightweight, free app (like Calculator or a basic game); if those also fail, the issue is a system-wide Store restriction rather than an HP-specific software glitch.
How to Fix It
To bypass the Store restriction and successfully install HP Smart for your 9015e, follow these precise steps:
- Disable Network Tunneling: Locate your VPN client (e.g., NordVPN, ExpressVPN, or Cisco AnyConnect) in the system tray. Right-click the icon and select "Disconnect" or "Exit." Ensure that "Kill Switch" features are disabled, as these can block all internet traffic if the VPN isn't active.
- Sync Region Settings: Go to Settings > Time & Language > Region. Ensure the "Country or region" is set to the actual location where you purchased the printer. If it is incorrect, change it and restart your PC.
- Flush the Store Cache: Press the Windows Key + R on your keyboard. In the Run box, type
wsreset.exeand press Enter. A blank black Command Prompt window will appear; do not close it. Wait 30-60 seconds until it closes automatically and the Microsoft Store opens on its own. - Execute the Install: Search for "HP Smart" in the Store. The "Get" button
