Argh, miscommunication due to terrible use of pronouns on my part lol. A vanilla Maya install on Windows will keep a "mayaRenderLog.txt" at "C:\Users\Gen\Documents\maya". Upload it here. And yes, the mayabatch.exe is indeed found in the C:\Program Files\Autodesk\MayaVersion\bin folder by default so if its there, then we can cross off that possibility.
