    Hello! Aditya. Thanks for the details.

    The error “Store Installer has stopped working” on Windows 7 Ultimate usually means the Windows Installer service (MSI) or the Windows Store app framework (if installed) is corrupted or misconfigured.

    Re-register Windows Installer

    1. Press Win + R, type cmd, then right-click → Run as administrator.
    2. Enter these two commands one by one:
      msiexec /unregister msiexec /regserver
    3. Restart your PC afterward.

    Make sure Windows Installer service is running

    1. Press Win + R, type services.msc, press Enter.
    2. Find Windows Installer.
      • If it’s Stopped, right-click → Start.
      • If it’s Running, right-click → Restart.

    Repair system files (if problem still happens)

    Sometimes the installer is failing because system components are corrupted.

    Open Command Prompt as Administrator again.

    1. Run:
      sfc /scannow
    2. Wait until 100% complete → then restart.

    Additionally, download Windows Installer 4.5 Redistributable from Microsoft’s official site (search: Windows Installer 4.5 Redistributable Microsoft Download Center).

    Install it → restart your PC.

    See if this helps. If you need further assistance, just let me know.

    Best regards,

    Kimberly
