It's possible that the installation process is encountering an error that is causing it to prompt you to restart the computer. One thing you can try is to check if there are any error messages or logs that might provide more information about what is causing the issue.

Another possibility is that there may be a conflict with other software or drivers on your system that is causing the installation process to fail. In this case, you may want to try uninstalling any software or drivers that may be conflicting with the MiniION software.

You may also want to try installing the software in safe mode, as this can help to identify any potential issues with your system that may be causing the installation to fail. To do this, you will need to restart your computer and press the appropriate key (usually F8 or F10) to access the advanced boot options menu. From there, you can select the "safe mode" option and try installing the software again.

If none of these suggestions help to resolve the issue, you may want to consider seeking further assistance from the manufacturer or a technical support service. They may be able to provide more specific guidance on troubleshooting the issue and getting the software installed correctly.
