Have you checked with the software's publisher as the Windows message suggests?– Steve RindsbergCommented Sep 23, 2018 at 5:38

are you 100% sure you meet all of these requirements? docs.docker.com/docker-for-windows/install/…– KeltariCommented Sep 23, 2018 at 6:05

I had docker installed previously on this pc. I just re-installed windows. The problem is that I can't even open the install dialog.– Totty.jsCommented Sep 23, 2018 at 6:41

@Totty.js ok, you reinstalled Windows, is iy fully patched to 1607 Anniversary Update, Build 14393 or later?– KeltariCommented Sep 23, 2018 at 8:25

Typically, that error is displayed for binaries that are an incompatible instruction set with the operating system. You'll get it with 16-bit (DOS or Win16) binaries on 64-bit Windows, 64-bit binaries on 32-bit Windows, and ARM or Itanium binaries (or other now-rare platforms that Windows used to support) on any x86-based system. Make very sure that you are installing the correct version for your computer. For example, since you reinstalled Windows recently, make sure you installed 64-bit Windows (32-bit Windows can't run 64-bit apps, even if using a 64-bit CPU).
Another possibility might be if you enabled software restrictions - especially if you configured your machine in Windows 10 S mode - in which case you'll get an error if you try to run software from an untrusted source (such as downloaded from the Internet). That's an unlikely answer, but "I reinstalled Windows and now I can't run a program I could before" is an unlikely problem.

Thanks, has been solved by downloading again. Not sure how it happened. My machine is 64bit and worked before so is very strange.– Totty.jsCommented Sep 23, 2018 at 10:56
