Frequently Asked Questions

1) What software do I need and where can I find them

  • We provide a stand-alone windows-executable version of the demos that does not require LabVIEW.
  • We also provide LabVIEW files. You will need LabVIEW and NI Vision development module to run the .vi files. 
  • LabVIEW and IMAQ can be purchased from National Instruments. UT students can download these for free from http://www.engr.utexas.edu/itg/

2) How do I run these demos ?

  • Download the zip file for the module that you are interested in.
  • Unzip the files. You will need winzip for unzipping these files.
  • For stand-alone windows executable version, double click on the setup.exe to install the demos. You can then access the demos from the Start->Programs menu in Windows
  • For the LabVIEW version, click on the .vi files in each Module for the LabVIEW demo to run.
3) Where are the image files for the demos 4)Problems / suggestions for demos
