# [solved]winrtrunner error "The environment variable ExtensionSdkDir is not set."

• I am trying to build my project using the Visual Studio compiler in Qt Creator, but whenever I run the program the following error appears:

``````qt.winrtrunner: Using the Appx profile.
qt.winrtrunner: The environment variable ExtensionSdkDir is not set.
qt.winrtrunner: The directory "" does not exist.
``````

• I have tried to add a "ExtensionSdkDir" in the build environment setting it to "C:\Program Files (x86)\Microsoft SDKs\Windows\v8.1\ExtensionSDKs". Then the following error occurs

``````qt.winrtrunner: Using the Appx profile.
