What is store installer how to fix it.Facing problem

I have the same problem on my Windows 7 Ultimate PC. I cannot install any programs because I get the error "Store installer has stopped working". I have tried all of the above suggestions to no avail. I ran scandisk; unregistered and re-registered msiexec; made sure the installer service was started; and when I tried to install Windows Installer 4.5 Redistributable it would not install because a newer version was already installed.

Any other suggestions or ideas would greatly;y be appreciated. Thanks.

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
