====== 33 ini Keys ======

//The ''LabVIEW.ini'' file contains configuration settings for how the LV IDE behaves. The file is located in the LV installation directory next to the `LabVIEW.exe`.//



===== Suppress popups =====

Use the following INI tokens (LabVIEW.ini) to suppress popups and auto-reporting errors:

    NIERShowFatalDialog = 0 
    NIERFatalAutoSend = true 
    NIERNonFatalAutoSend = true 
    NIERShowNonFatalDialogOnExit = false 
    NIERSendDialogClose = true autoerr = 3 
    DWarnDialog = false

===== App (*.exe) INI =====

When building an executable (EXE-file) it comes with an INI-file of the same name (e.g. "My-App.exe" and "My-App.ini"). This INI-file contains several configuration options regarding the LabVIEW runtime environment in which the application is executed.

==== Run the same app in multiple instances ====

Normally, you can run a LabVIEW executable only once at a time. It's possible to change this behavior by adding the following line to the INI-file:

''allowmultipleinstances = TRUE''
