None of what follows is true, this is just a rhetorical question.
Suppose I find a big horrible bug in LabVIEW, the kind of bug that only happens at runtime and that only happens when my LV build EXE runs on Windows 7 64bit, never happens when my EXE is ran on Windows 7 32bit. So I would contact NI Support, give them the source code (~2k VIs) and the details to reproduce, try to narrow down the issue by eliminating parts of the code, etc... and then after a couple of months no solution has been found so I'm left with my wounds to lick, being told I should try and convince those who use my product that they should only use a 32 bit OS.
And let's also suppose that my company is a gold member of the NI alliance program, and that I've already sold 50+ licences of my product, each of which also includes about $10k of NI products.
If anyone was ever in a similar situation, what could they do to sway NI to put real effort into solving the issue?
But again this is just a rhetorical question!
