I modified the gui, uutdlg.c, in modelsupport2.prj to include a Model # and Assembly # on the gui. I also added required strings to the TestStandStrings.ini file. The project compiled fine and I created a custom engine to install. However, when I run the apllication as soon as the user enters the information into the UUT gui, Test Stand just exits. No errors, no anything, it just shuts down ?????????? Any help??
