I have several PI systems to upgrade sometime in the next few years and am trying to estimate the cost of doing so. The versions are 3.4.380, 3.4.385 and 3.4.390. All of these systems are available in 32 and 64 bit. I would like to be able to tell the bit version with PI-SMT but don't see how. Even the Windows Registry stores ..PISystem\PI in both HKLM\SOFTWARE and HKLM\SOFTWARE\Wow6432Node.
