Hey !What does the actual render log say? By default on Windows, its in your username/my documents/maya folder or your operating system's equivalent. You have Maya reinstalled Maya and the mayabatch.exe should be there but double check if it's at the specified path.
I did upload the log just now, I'm not really sure what might be causing the issue. it's the first time I work with fluids and vfx renders especially if it was tga sequences, what I always do is animation with tga images sequences and it always works fine with me.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.
