Like all other versions of the Windows Operating System, Windows 10 cannot install a program using Windows Installer while the installation for another program is already running. If a user does try to install a program via Windows Installer while another installation is already running, Windows displays an error message that reads: “Error 1500. Another installation is in progress. You must complete that
installation before continuing this one.” If you see this error message while trying to install an application, simply wait for the already running installation to finish or close the already running installation and proceed with the new one. Unfortunately, there have been reports of this error message sometimes showing up when Windows 10 users try to install a program even though there is no other installation running in the background and/or any previously running
installations have already finished. If you are trying to install an application on a Windows 10 computer and are being met with Error 1500 even though there are no other installations running in the background, the following are some of the most effective solutions that you can use to try and resolve the problem: Solution 1: Run an SFC scanRunning an SFC scan is the most basic countermeasure to a problem such as Error 1500 as it is capable of analyzing all system files for corruption and other issues and repairing/replacing any system files that may be causing problems. To run an SFC scan on a Windows 10 computer, simply follow this guide. Solution 2: Close background processes that may be causing the problemThe Error 1500 error message can be triggered by lingering background processes from installations that were previously running on the affected computer. If residual background processes from previous program installations are causing this problem, you can fix it by simply closing the offending background processes in the Task Manager. To do so, you need to:
Solution 3: Delete any active installation status references from the RegistryWhen an installation is in progress, an active installation status reference is added to the computer’s Registry, and this reference is removed once the installation finishes. However, an installation may sometimes fail to remove the active installation status reference from the Registry, and this can lead to the user seeing Error 1500 the next time they try to install a program on their computer. To manually delete any active installation status references from the Registry, you need to:
HKEY_LOCAL_MACHINE > Software > Microsoft > Windows > Installer
Once done, try running the installation you were experiencing the problem with before and see check to see whether or not the problem has been fixed. Solution 4: Stop and then restart the Windows Installer serviceSince you are experiencing this issue because Windows Installer thinks that it is trying to install two programs on your computer at the same time instead of just one, stopping and then restarting the Windows Installer service is a pretty solid bet for getting rid of this issue if none of the solutions listed and described above worked for you. In order to apply this solution to your computer, you need to:
Run the installation that was displaying Error 1500 to you before and see whether or not the installation completes successfully this time.
