WINDOWS INSTALLER NOT RUNNING

Question

TRYING TO INSTALL A PROGRAM THAT RUNS ON OTHER WINDOWS 11 COMPUTERS WON'T RUN ON THIS NEW ONE

Answer 1

Hi Fredric Volino,

Welcome to the Microsoft Q&A forum.

If a program runs successfully on other Windows 11 computers but not on this new device, it’s usually related to system configuration, installer services, or compatibility settings. Please try the suggested troubleshooting steps from Q&A Assist:

Confirm Windows Installer is available since the program installer relies on a built‑in Windows service to run correctly.

• Open Command Prompt, type MSIExec and press Enter
• If no error appears, the installer engine is available and working as expected.

Please also check for Windows 11 mode and compatibility as some new PCs ship with additional restrictions or newer builds.

• Verify the device is not in Windows 11 S mode, which limits non‑Store apps
• If the app is older, run the Program Compatibility Troubleshooter from the app’s properties to apply recommended settings.

You can use a fresh, local copy of the installer to retry

• Re‑download the installer from the software provider
• Save it to your local device (for example, Downloads)
• Right‑click the file and select Run as administrator.

Answer 2

Follow these steps on the new Windows 11 PC to troubleshoot Windows Installer not running:

1. Verify that the Windows Installer engine works
   1. Select Start, type cmd, and press Enter.
   2. In the Command Prompt, type:

            MSIExec
      

      and press Enter.
   3. If no error appears, the Windows Installer engine is functioning. If an error message appears, note the exact text and search for it to get specific troubleshooting steps.
2. Make sure the Windows Installer service is enabled and started
   1. Select Start, type services.msc, and press Enter.
   2. In Services, find Windows Installer.
   3. Right‑click Windows Installer and select Properties.
   4. If Startup type is set to Disabled, change it to Manual and select OK.
   5. Right‑click Windows Installer again and select Start.
   6. Try installing the program again.
3. Try a different installation method or fresh installer
   1. If installing from CD/DVD or USB, browse to the media and run the setup program directly (typically Setup.exe, Install.exe, or Autorun.exe).
   2. If installing from a download, re‑download the installer, choose Save (not Run), save it to a local folder (like Downloads), then run it from there.
   3. If the installer was downloaded some time ago, check the software publisher’s site for a newer version and use that.
4. Check for corrupted or unreadable installation media
   • If using a CD/DVD, clean the disc with a soft, lint‑free cloth, wiping from the center outward.
   • If possible, copy all installation files from the disc or network share to a local folder on the PC and run the installer from that folder.
5. Perform a clean boot to rule out interference from other apps
   1. Select Start, type msconfig, and open System Configuration.
   2. On the General tab, select Selective startup and clear Load startup items.
   3. Go to the Services tab, select Hide all Microsoft services, then select Disable all.
   4. Select OK and Restart.
   5. After restart, try installing the program again.
   6. When finished, open msconfig again and set Normal startup on the General tab, then restart to return to normal operation.
6. Use the Program Install and Uninstall troubleshooter (if the install is blocked or partially fails)
   1. Download and run the Program Install and Uninstall troubleshooter.
   2. Follow the on‑screen steps to detect and repair issues that block installation or that involve corrupted installer registry keys.

If the installer still will not run on this PC but works on others, and Windows Installer is confirmed to be running correctly, contact the program’s manufacturer for app‑specific compatibility or installer issues on this particular Windows 11 build.
