When you get the ‘NSIS Installer Error’ it means that malware has changed or broken the installer. Windows shows the error message to stop the user from installing anything else. This error happens when the installer doesn’t check its own integrity before it starts. So, if the user keeps running the installer, the software could be damaged.
The installers that are made can install, remove, and extract files, change system settings, and so on. Users can quickly and successfully install a certain programme because of the installer. Since the installer is made from script files, users can easily and fully control every part of it.
Users could also run into problems when using installers made by NSIS to install applications, programmes, or drivers. They might not be able to install something and get an error message like “Error launching installer” or “Installer integrity check has failed” in a pop-up window called “NSIS Error.”
9 Ways to Fix ‘NSIS Installer Error’ Issue on Windows 11/10
Install the Program Using Command Prompt
- Press the Windows key, type cmd, and click on Command Prompt.
- Next, open the File Explorer and locate the installer file.
- Drag and drop the file onto the Command Prompt window to add the file path.
- Hit Enter to execute the file and run the installer.
Run the Program in Compatibility Mode
An app or installer can be forced to run in compatibility mode. In this mode, the app uses the settings for an older version of the Windows OS. This is helpful if the app was made to run on older versions of Windows.
- Locate the installer you want to install.
- Right-click on the installer file and select Properties.
- In the Properties window, open the Compatibility tab.
- Check Run this program in compatibility mode for option. Then click the drop-down and select the Windows version older than your current version (Windows 8, 7, XP, so on).
- Click Apply and OK to save the changes.
- Run the installer again and check if the setup completes without the error.
Move the Setup File to a Different Directory
Moving the installer to a different folder can help you run the setup file without the NSIS error. To do this, open File Explorer and locate the setup file you want to run. Select the file and press Ctrl + C to copy it to your clipboard. Next, create a new folder on another drive if available and paste the copied file with Ctrl + V shortcut. When creating a new folder, keep the name simple and avoid using any special or non-English characters.
If the problem keeps happening, try running the installer from a different disc drive. If you only have one drive, you should use a USB flash drive. Move the setup file to your USB stick and run it from there. This is more of a workaround, but it should help if an installer is giving you trouble.
Scan your computer for viruses
If none of these work, your computer may have a virus that stops it from installing software. Until you get rid of the virus, you won’t be able to do much with it. You can do this with any antivirus programme you want, but make sure to run a full, thorough scan instead of a quick one.
A quick scan misses a lot of files and folders that could contain the virus-infected file that is causing the problem. The NSIS error could be caused by a badly broken setup file or a bug in the operating system that sends a false error message. Either way, one of the solutions above will help you fix the problem.
Check System Language
- Hold the Windows Key and Press X and choose Control Panel.
- In Control Panel type Language
- From the Language pane, choose Change date, time or number formats from the left pane and then go to the Administrative tab.
- Choose Change System Locale to your country’s language. If the software is in a different language, then you can change the Language but that will also change Language and Keyboard layout.
Rename the installer
This is extremely simple, and unlikely to trigger the NSIS error, but you can try it as it has been known to help. Locate the setup file, and Right-click it, and select Rename from the list. Click it, and press F2 on your keyboard. Change the name to something simple which only has one word. For example, change it to Softwarenamesetup.exe. Try running the setup again and see if it works.
