Hi.  I have been trying for several days to get the TI-Nspire emulator installed on my computer, but I can't extract the boot 2 image from the .tno file.  I change the file extension to *.zip and Windows gives an error message saying that the files cannot be extracted.  In the setup video, it looks like some third party extraction software is being used, not just the built in Windows extractor.  Does anyone know how I can extract the file to get the emulator working? Thank you for your help!
