Prerequisite command line arguments not being passed from Setup.exe..
I just installed IS 2020 and was doing a little testing and found an error with a previously functional prerequisite called from the setup.exe. It's an .exe and in the prerequisite setting ' Specify the command line for the application:' is set to [ProductLanguage]. I've attached an image of the setting.
The prerequisite .exe first grabs the command line arguments array and element 0 is the path to the running .exe, while element 1 should be the product language identifier. However I can see that there is no element 1, which means the command line argument is no longer making it or being passed from the setup.exe (there is a language selection box displayed at initiation of the setup.exe) to the prerequisite .exe.
