This message notifies you that profiling cannot be started. AQTime displays it when you attempt to profile a project and the first module added to this project is not a .NET module. This typically occurs when a .NET application is profiled together with a native-code DLL (a non-.NET module) and the DLL has been added to the project before the EXE. To fix the problem, first open the .NET module in AQTime and after this add the native-code modules to the project.
