Errors occur when you run the Windows App Certification Kit on C++ Store apps


When you run the Windows App Certification Kit version 3.4 on C++ Store apps, an update to the App Inventory may cause errors in the Supported API test. Additionally, you may see error messages that resemble the following in the Supported API test: 

API strtoll in msvcr120_app.dll is not supported for this application type. TestComponent.dll calls this API.

The files that are referenced in these errors are part of a framework. Your application did not create these files. 


To work around this issue, uninstall KB 2976978, and then rerun the Windows App Certification Kit.
