How to fix "Another installation is in progress" error – Progeny Genealogy

If you encounter an error "another installation is in progress" when trying to install, it is because the Windows Installer Service is still running.

Please do the following:

1. (Windows 7) Click on the Start button, right-click on "Computer", click on "Manage":

(Windows 8, Windows 10): Press the Windows + R keys, enter "services.msc", press Enter. Make sure you are Administrator.

2. Click on "Services":

3. Right-click on the Windows Installer Service, click on "Properties":

4. If you’re having the problem, the Windows Installer service is started, and the Stop button is disabled.

Change Startup type to “Disabled”, click OK, and reboot your computer. This stops the service.

After your computer reboots, again open Computer Management, open Windows Installer Properties, and change the Startup type back to Manual.
