I am very new to OpenStudio, and am trying to run a simulation for a very simple model I made. When I run the simulation, it fails after "Starting Simulation" and just says "Failed" with no explanation. However, when I click on "Show Simulation" and go into the run.log file I find this error:

[13:50:27.575912 ERROR] Found error in state 'simulation' with message [":/ruby/2.2.0/gems/openstudio-workflow-1.3.2/lib/openstudio/workflow/util/energyplus.rb failed with Invalid argument - \"C:\\openstudio-2.5.0\\bin\\..\\EnergyPlus\\ExpandObjects.exe\", :/ruby/2.2.0/gems/openstudio-workflow-1.3.2/lib/openstudio/workflow/util/energyplus.rb:103:in `popen'\n:/ruby/2.2.0/gems/openstudio-workflow-1.3.2/lib/openstudio/workflow/util/energyplus.rb:103:in `block in call_energyplus'\n:/ruby/2.2.0/gems/openstudio-workflow-1.3.2/lib/openstudio/workflow/util/energyplus.rb:102:in `open'\n:/ruby/2.2.0/gems/openstudio-workflow-1.3.2/lib/openstudio/workflow/util/energyplus.rb:102:in `call_energyplus'\n:/ruby/2.2.0/gems/openstudio-workflow-1.3.2/lib/openstudio/workflow/jobs/run_energyplus.rb:44:in `perform'\n:/ruby/2.2.0/gems/openstudio-workflow-1.3.2/lib/openstudio/workflow/run.rb:261:in `step'\n:/ruby/2.2.0/gems/openstudio-workflow-1.3.2/lib/openstudio/workflow/run.rb:210:in `run'\n:/openstudio_cli.rb:821:in `execute'\n:/openstudio_cli.rb:620:in `execute'\n:/openstudio_cli.rb:1547:in `<main>'\neval:85:in `eval'\neval:85:in `require_embedded_absolute'\neval:70:in `block in require'\neval:64:in `each'\neval:64:in `require'\neval:2:in `<main>'::/ruby/2.2.0/gems/openstudio-workflow-1.3.2/lib/openstudio/workflow/util/energyplus.rb:165:in `rescue in call_energyplus'\n:/ruby/2.2.0/gems/openstudio-workflow-1.3.2/lib/openstudio/workflow/util/energyplus.rb:172:in `call_energyplus'\n:/ruby/2.2.0/gems/openstudio-workflow-1.3.2/lib/openstudio/workflow/jobs/run_energyplus.rb:44:in `perform'\n:/ruby/2.2.0/gems/openstudio-workflow-1.3.2/lib/openstudio/workflow/run.rb:261:in `step'\n:/ruby/2.2.0/gems/openstudio-workflow-1.3.2/lib/openstudio/workflow/run.rb:210:in `run'\n:/openstudio_cli.rb:821:in `execute'\n:/openstudio_cli.rb:620:in `execute'\n:/openstudio_cli.rb:1547:in `<main>'\neval:85:in `eval'\neval:85:in `require_embedded_absolute'\neval:70:in `block in require'\neval:64:in `each'\neval:64:in `require'\neval:2:in `<main>'"]}

Can anyone help resolve this?
