Problem: How to fix “Installation is prohibited by system policy” error?

Hello. I recently tried to install my Intel Wireless Adapters from the official Intel site and it failed with the error ‘This installation is prohibited by system policy. Contact your administrator ». I have not changed anything in my PC settings since I installed Windows, although I have recently modified the router. What’s going on?

Resolved answer

Device drivers are one of the most important components of the Windows operating system, allowing software and hardware to communicate properly. Although some devices, such as dedicated graphics cards, can function minimally without them, the absence of drivers can prevent the hardware from functioning.

Since we are talking about res adapters here, the error “This installation is prohibited by System policy” should prevent major functions on this device, including WiFi, as well as Bluetooth connections. Certainly if no ethernet is available to replace the WiFi connection, this can become a bigger problem, as the internet connection would not be accessible.

The error “This installation is prohibited by System policy” can occur not only when installing wireless drivers. Users have said that they have received the same error when they have installed Autocad (Error code 1625, 509), Python (0x80070659), mouse drivers (G500), and other softwares.

As the error message itself suggests, the reason why it occurs is not having sufficient rights to install new software, regardless of whether they are drivers or applications. Although it may seem that running the installer with administrator rights may be sufficient, this is usually not the case here (although you should definitely try the first solution), so other permissions in the settings need to be altered.
