Hello guys, I am using Labview 2013 student version to write code for data acquisition from an IC Engine. I have to induct the code in a Labview 2009 version in my college lab to run on the engine there. I try to save the code for previous versions but when I try to run it on 2009 version, it says 'Error 3 : Front panel cannot be loaded'. What should I do to continue using Labview 2013 and transfer code to 2009. I have licence for 2009 version too, but it doesn't detect any of the DAQmx vi's even if I have installed them, which forces me to code in 2013. Please help me in solving this issue. Thanks.
