Paul, Running older versions of the IDV is not recommended. I am curious to know what errors you are running into. It may be a simple matter of updating your graphics card driver. On the computers in question, please download and install the latest version of the IDV corresponding to your operating system. http://www.unidata.ucar.edu/downloads/idv/current/index.jsp After installation, open a Command Prompt window. Run the program C:\Program Files\IDV_52\runIDV.bat What errors do you see? Best, Unidata IDV Support > Greetings, > > I used IDV 7 years ago to teach Meteorology.
