Hello,
Actually I was facing the same issue: I was migrating a large project from LV2009 to LV 2012 (more than 500 Vis) and after checking all of my dependancies, the white arrow stayed grey and I had got the given error : "Compiler Error: Invalid size in _InstSize:22".
There was no indication on which VI was root of the problem.
I made a reserach on all "In range and coerce function" and fix the one which had a "bad conversion". Actually the input was an U16, but coming from an enum and the Range were only U16 without any casting. I change the code and now all is working.
Thanks very much for the support.
