I have reinstalled visualstudios2015, and it did not fix my problem. I’m not sure if it matters, but I don’t have an ADM processor, and it is present in the error. I have built this project before, and it worked. I re-downloaded it from git, and now it is not working. Any help would be appreciated!

Hi Allergybiscuit,

Based on the output, my intuition is that you are missing the Windows 8 SDK which would have installed the .NET 4.5 framework.

You can find a download here:

> **[Windows SDK and emulator archive](https://developer.microsoft.com/en-us/windows/downloads/sdk-archive/)**
>
> Download and install previous Windows SDK and emulator releases for development on earlier versions of the Windows and Windows phone platforms.

Let me know if this fixed your issue or if you continue to receive this error afterward.

Cheers,

Jonathan
