If you try to install UltraAV on a computer running an ARM processor, you will get the message This device is not supported. Unfortunately, UltraAV can't be installed on devices that use an ARM processor.
You get that message because your device is using an ARM processor and is running an ARM version of Windows. At this time, UltraAV can not be installed on Windows computers running an ARM processor.
You can still use many of the other services Ultra Antivirus offer, such as UltraVPN, Ultra Identity, Total Cleaner, and PassWatch.
See the article UltraAV System Requirements for more information on supported systems.
