Error install PGI on Windows

Hi,

when I install PGI on my Windows system i get this error:
External Media

I have made this installation in other machine I hadn’t any problem.

Thanks.

If the PGI download for Windows installed on another system,
then the same download is probably not corrupted. If it was a separate
download, perhaps you can determine if the checksum of the download
matches the checksum posted on the download page when you start it.

What happens next depends on what version of Windows you have.
If Win10, make sure you have installed Win10 SDK.
If Win8 or Win8.1, make sure you have installed any windows updates,
before installing Win10 SDK from Windows Dev Center | Microsoft Developer .

If Win7, install any updates, and then install an older version of Win10 SDK
from Windows SDK and emulator archive | Microsoft Developer .

Once the Win10 SDK is installed, then install the 16.9 wokstation.
