Generated a load module as cooperative code and receive the below error during build (For this example, the cooperative server for the sample model was used):
NMAKE : fatal error U1073: '"C:\Program Files (x86)\CA\Gen86\Gen\Samples\Models\sample.ief\c\P900.HHK"'
Component: Gen Workstation Toolset
Verify that the "TP monitor." setting in the Toolset Generation Defaults is correct, the wrong setting can lead to the fatal error U1073.
In this case, the load module is a server module (no Window), recommendation is to change the "TP Monitor:" setting from 'WINDOWS' to 'IEFAE' and regenerate the module to resolve.
