Windows App Certification Kit Warning

It makes no sense to use WACK on your project. It was made to verify WinRT apps, the kind that are published through the Store and run on Windows 8.x or Windows Phone. They need to be safe to run in a very restricted sandbox that makes a very small subset of the winapi available. Limited for security, deployment and power-consumption reasons, what WACK verifies. A desktop DLL like msvcr100.dll cannot meet them. Such apps are built with another CRT, vccorlibxxx.dll

You cannot build such an app with VS2010, VS2012 or higher required. Nor can it run on Win7. You simply need to stop using the tool.

Update: it does appear that WACK was updated in the 8.1 SDK to also verify Windows Logo requirements for desktop apps. This is obscure. Judging from the command help that's displayed when I run appcert.exe /? in an elevated command prompt, you must first create an installer for your app. Then you can run appcert with the -apptype desktop and the -setuppath yourinstaller.exe to have it perform the validation. Some additional command line options appear to matter, like -appusage. I don't know what they mean.

Do keep in mind that this is only useful if you need the Windows Logo certification. There ought to be additional information in the logo program documentation about this. Consider contacting Microsoft if you have Windows Logo program questions.
