This error message appears when you’re trying to install something else on your computer. You might see this message if you try to install an app, driver, or some other type of software. If you see this message, don’t panic. Instead, follow our guide to resolve the issue.
This is a common problem among people who want to install several applications at once. They open the installer file, select the desired apps, hit Next, and suddenly they see an error message saying “Another application is being installed.”
There are many reasons why you might encounter this error. An installer error message usually indicates there’s something wrong with an application being installed. This could mean anything from a missing file to a corrupted executable.
If you’re still having issues after trying those steps, try checking out our troubleshooting guide. If you continue to experience problems, contact customer support.
Restart your computer
If all else fails, you may want to try restarting the computer. Many times, this will fix issues such as a corrupted registry or a virus infection. You can do this easily by pressing the power button on your PC and selecting Restart. This will shut down all running programs and services, reboot your operating system, and start up the applications you had open prior to turning off the machine.
You may even find that rebooting fixes some problems that are specific to Windows 10. For example, if you recently installed a program that did something unusual to your system, like changing the way your mouse worked or installing a bunch of unnecessary software, you might want to try rebooting to see if that helps.
Scan your computer for viruses
A virus scanner is an essential part of keeping your computer clean. You might think that it’s enough to just download a program and let it do its thing, but there are some things that you don’t want to risk. If you don’t know what you’re doing, you could accidentally make matters worse. So, why not take the extra step and use a free online virus scanner? In fact, we recommend running one every single day.
- OpenWindows Defender.
- Go to the Virus & threat protection tab.
- Click Scan options.
- Click Scan now.
- If you see anything suspicious, open the file and delete it.
- If you don’t know what to look for, take a screenshot and post it online.
Stop the installation manually
If the app’s installation hasn’t finished after waiting for a reasonable amount of time, you might want to try quitting the installer yourself. This way, you won’t have to worry about accidentally closing out of the installer without finishing the installation.
- Right-click the taskbar and select Task Manager.
- Go to the Processes tab.
- Look for the installers/EXE/MSIs process and select it.
- Then click the End task button at the bottom right.
- Now you can safely close down the installer window.
Let the installation run its course
When you install an app on Android, it usually takes about 10 seconds to start downloading and installing. But some apps are taking longer than expected to finish. If you see a progress bar during installation, don’t worry — just wait patiently.
Apps that download additional files or dependencies may take a while to load. You might notice that your phone starts to vibrate every few seconds. This isn’t because you’re getting a call; it’s because the app needs to fetch data from the internet. Don’t worry though — most apps won’t do anything until they’ve finished loading.
If you still aren’t sure what’s happening, try waiting at least 15 minutes before retrying the installation.
Close the Windows Installer process in Task Manager
Don’t quit the installation. If you don’t want to uninstall the program, make sure you know how to properly terminate the installation process.
Right-click Start and open Task Manager from the Power User menu. Navigate to the Details tab and look for the entry called msiexec.exe. Click on it and end the process (end task). You might want to try restarting the installation again, too.
If you want to completely uninstall the program, follow these steps:
1. Select the program and click Uninstall.
2. Wait for the uninstallation to finish.
3. Restart your PC.
4. Reinstall the program.
Make sure third-party applications are disabled before installing
Windows Installer keeps track of every single application that you install on your computer. This includes both software programs and drivers. If you want to avoid having it running all the time, you can disable it via Task Manager.
- Right-click on the Taskbar then select Open Task Manager.
- Select the processes tab.
- Now go down to the Services section.
- You will see a list of all installed services. Scroll down to find Windows Installer Service.
- Click on the Start button.
- Then press Ctrl+Alt+Delto to bring up the task manager window.
- Scroll down to the Processes tab.
- Find Windows Installer Service. Click on End process.
- Confirm changes.
- Restart your PC and try to install the program at hand again to make sure everything works fine.
