Are you installing as administrator?
Also, is Windows and your main drivers fully up to date?
This indicates a possible malware threat. What antivirus/anti-malware application are you using?The program will not install and I keep getting this warning:
SettingsModifier:Win32/HostsFileHijack
Is this a hacked file or is it safe?
If it is safe how can I install it?
Most likely false positive - it happens. But infected software releases happened too. Download latest MSI Dragon Center installer and try then.

On the one hand one would expect downloads on the MSI site to be safe, but on the other hand, why does the MSI Dragon software need to modify the Windows Hosts file? It does seem a tad suspicious. If you're at all concerned then wait a week or so and download the software again just in case something malicious has found its way onto the MSI download servers.
If you're determined to proceed then you can turn off Windows Security temporarily so head over to Settings -> Update & Security -> Windows security -> Open Windows Security -> Virus and Threat Protection -> Manage Settings. -> toggle "Real-time Protection" to the Off position. Remember to re-enable it when you've completed the software installation.
