When following the started guide Hello World example of the differential equation, I got to running the model then got the following error:
Initiation of "HelloWorld" as experiment "HelloWorld 1" started at 05:25:43
Error: Error building simulator. Buildlog: command mingw-g++ not found. Error: Error building simulator. Buildlog: command "C:\Program Files (x86)\Wolfram Research\SystemModeler 3.0.2\bin../bin/Compile" not found.
error: No executable generated.C:/Users/Jose/AppData/Local/Temp/sme142813954341.exe
It looks like it lost the compiler . Any help?
Can you try with SystemModeler 4.1? This problem is only related to version 3 of SystemModeler.
