Prerequisite to avoid Compiler error while running simulation

I'm writting this wiki because we have often question about this error msg: "error compiling DELMIA simulation model"

To use 100% DELMIA fabrication simulation functionalities (machine simulation at PO or MP level...)  it is mandatory  to install a compiler (used also for DELMIA Robotic and DYMOLA) .

Else the system return an error msg when you start the simulation 

In the Machining landing page (displayed when yu load app the first time or can be reload via ? ) you have a ‘check install' to control the instalation

if the compiler is not installed on your machine , a documentation is available in the instal path to help you
