Error Running EP FMU export on Simulink

edit

I was trying to run an EPFMU export on simulink, when using an EnergyPlus FMU export on simulink, where my idf file has a running period of 31 days with 1 timestep per hour, the run is stopped by the following error:

Log from FMU: [category:error, status:fmiError] fmiInitializeSlave: A valid time step could not be determined. Log from FMU: [category:error, status:fmiError] fmiInitializeSlave: Can't read time step file.

My stop time of simulink is multiples of 86400. Can someone help please ? Thanks in advance.

**Update: I've tried different versions of Visual Studio including 2013, also I've tried using the Energy+idd of versions 8.6, 8.9 and 9.x. I tried to uninstall all EP versions and keep only one. I've tried replacing the RunPeriod object in the IDF order in the idf text editor as per the discussion of issue #30 (https://github.com/lbl-srg/EnergyPlus...) but still had no luck.

The fmu file generates fine but the simulation stops at the same stage krzysztofarendt experienced in issue#30 with the exact error message related to timestep.

**Update2: I've set the run period in the idf file for 1 day and identified a fixed timestep for the simulink. Now the simulation runs for ever and doesn't allow to pause or stop. No results. I wanted to try the fmu on pyfmi, but when installing the library through python setup.py install --fmil-home=C:\Python27\Lib and python setup.py install --fmil-home=C:\Python27\Lib\FMI_Library , get error option --fmil-home not recognized.
