In addition to the VirusTotal method of testing the MSI installer,
you can scan it with Windows Microsoft Defender on your computer. Follow these steps.
Open Windows File Explorer (click Windows Start > All Programs > Windows System > File Explorer ) or use your favorite file manager app.
Navigate to the Downloads folder.
Right-mouse click the MSI Installer file.
From the context menu, pick Scan with Microsoft Defender. The scan should report "0 threats found".
