CNX2 <....> 32 vs 64-bit <....> But, how do you know?

That's a very fair question Jerry! And quite a surprise that the Nik developers didn't simply add a quick '32' or '64' prefix or suffix to the Version number on that "About ..." box!

I see from your profile that you're running Windows, but I don't know whether you've got Windows 7 or XP ... but if you're running Windows 7 then you may have spotted the different install-Paths for the 64-bit CNX2 version and the 32-bit CNX2 version that I mentioned in my post #65 below, and hopefully that'll be a clue. (I'm not certain of the install paths for Windows XP 64-bit, so I won't try to quote them just now.)

If you are on Windows 7 64-bit, and if your CNX2 is being started from the "C:\Program Files (x86)\Nikon\" folder then you're definitely running the 32-bit version of CNX2.

(Of course, if your Windows 7 is itself "just" the 32-bit Operating System then you won't even see a "C:\Program Files (x86)\Nikon\" folder on your C: drive, as that "(x86)" part only exists on 64-bit versions of Windows.)

While I'm here, though not to reply especially to your query Jerry, let me add two other notes that might help somebody else check their 64-bit versus 32-bit status, both for their Windows and their version of CNX2 ...

Either of these Microsoft links will help us check if our Operating System is 64-bit or 32-bit -

B. 32-bit-and-64-bit-Windows-frequently-asked-questions

(Note that the terms "x64" and (confusingly) "x86" are synonymous with 64-bit and 32-bit respectively.)

And now for a more complex hint to tell for certain whether your CNX2 is the 64-bit version or not ... and you'd be forgiven for skipping this entirely if you aren't keen on running techie tools on your PC -

(I'm darned certain that there will be another way to do the following check on our CNX2 "bit length", using tools already on our PCs without recourse to the internet or the clever techie utility I mention below ... but it would take me an even longer time to locate and describe the 'ideal' permutation of Control Panel stuff + built-in-utility tool-tweaks than the following "universal" suggestion - sorry!)

The Windows Sysinternals web-site is highly regarded, and their free utilities are fully endorsed by Microsoft (proven by the fact that Microsoft bought them out a few years ago!).

More than one of the free Sysinternals tools will report whether your (running) version of capture NX is the 64-bit version or the 32-bit version, but I'd recommend the not-too-exotic "Process Explorer" for this purpose ...

Sysinternals - Process Explorer

(I'll skip the download & extract stuff, as it's all nearly routine nowadays!)

With Capture NX2 running in the background, run this Process Explorer utility and give it a few seconds to populate its colourful table of "things happening now" on your PC ... then do the following:

1. Click on the "Process" column to sort the list of processes alphabetically.

2. Look for the column headed "Image Type" (one of the columns towards the right).

3. Browse down that column until you see the line for your "Capture NX 2" - not far from the top

4. Your Capture NX 2 "Image Type" will be shown as either "64-bit" or "32-bit"!

Easy peasy ... but as I say above, my ol' (retired) techie-support gut instinct tells me there will be at least one easier way of answering that CNX2 question ... but it's way past my bed-time again.

Sorry for such an extended (and strictly speaking unsolicited!) 'tip', but isn't it a surprise how opaque these details are of our Operating Systems and our essential software tools??!!
