This is the output from debugview:
[9348] installed exception handler for C:\Program Files (x86)\Zorro\mt4R.DLL
[9348] <0> Create: Failed to execute C : 2
[9348] <0> Create: Error: R did not start: 2
[9348] RInit: RHandle = BD8E63C (198764092)
[9348] RDeinit: RHandle = BD8E63C (198764092)
[9348] <-1> TRConsole: destroying
Especially this line:
[9348] <0> Create: Failed to execute C : 2
seems interesting
