Hi Javed,ÂI tried running the file you mentioned with EP 9.2.0 on my windows 64 bit system and it runs fine. (see attached)ÂI would suggest uninstalling the EnergyPlus 9.2.0 and reinstall it.ÂIf the problem persists, let me know.ÂRegards,Maharshi PathakRBRG, NRELOn Thu, Oct 24, 2019 at 12:04 PM Javed Iqbal eee.javed@xxxxxxxxx [EnergyPlus_Support] <EnergyPlus_Support@xxxxxxxxxxxxxxx> wrote:ÂHello, I am trying to test an example file 'SmallOffice_CentralDOAS.idf' [Eplus v9.2] for some reasons.
