It was not very clear to me but now I understand why there is no windows version of this script. You need to run it from the shell of your GNSVM and not from your main operating system. This is a Layer 2 IOU images. At the time of writing it is considered one of the best if not the best L2 IOU image. I personally just changed the file extension from '.nov32015highiron' to '.bin' and imported it into GNS3 but apparently there are other ways to do this too.

Cisco IOS-On-UNIX is a fully working version of Cisco IOS that runs as a user mode Linux process.
IOU supports all Cisco IOS platform independent protocols and features. IOU allows you to build out a network topology on a single PC without the need for physical routers. This is useful for validating network designs, proof-of-concept testing, and certification self-study.
This is the Linux-based version, this application run only in Linux. If you are a MS Windows user, you can install a Linux operating system in a dual boot scheme or in a virtual machine such VirtualBox or Vmware Workstation.
Here are some tutorials. Please, pay special attention to the chapter of Cisco IOU Error Messages.
