What version is "LabVIEW 2002"? Back then, the year was not part of the version number. I estimate it would have been about LabVIEW 6.
This chart will help to tell what you need.
If it happens to be LV 5.1, then you need to open it and save it in a version between 6.0 and 8.2. Then you can then open that one in versions newer than 8.2
Thanks for the reply.
Sorry i made a typo. Its 2012 , not 2002.
While i open 2012 VI on a 2019 version, it is showing errors in calling libraries.
2020 will open 2012 just fine.
If you are getting errors because of missing libraries, that means you don't have something installed. What do the error messages say? What libraries?
Perhaps they are instrument drivers you need to download.
