If there's more than one version of VNX on Nikon's website, are you downloading the 64-bit version and not the 32?
Ok i rechecked and yes it's 64 bit.
What else can I do?
Stop battling the tide, and give up on Nikon software. I know I personally gave up on it after soooooo many years battling Nikon Capture, and its continual habit of being crash-prone on Windows, crash-prone on Mac OS, buggy, poorly-featured, crappy interface design, slow-to-be-updated, or "no longer updated" on new Mac OS variants, just to name a few of the issues with Nikon software. Thom Hogan has been very critical of Nikon's software problems, which are many, and long-duration issues. The software offerings Nikon has released since Capture version 1.0 have always been memory-inefficient, and, well, very far behind state of the art except for maybe the first 12 months of raw image development as a "thing".
Nikon software seems dedicated to the idea that a HANDFUL of images will be processed, and no more. The idea that the software needs to be rock-steady, fast, reliable, and updated in synch with new software from the OS manufacturers is something that has just not registered with Nikon, Japan.
Nikon "farms out" its software development to third parties, and has for years; Nikon software has just not established the wide-ranging reliability that Adobe (and others) has been able to establish. Sure--there are a FEW people who have working versions of some Nikon software, but there are tens of thousands of web-forum examples and complaints/pleas regarding defective/buggy/crash-prone/problematic Nikon software. The thing is--the software industry is something Nikon has NO REAL experience in--they HIRE it done, and it has been done BADLY for going on 15 years now. Thom says he can no longer recommend Nikon software. I stopped using Nikon Capture around version 4.1...because it was sloooow, and tended to CRASH if more than ten files were batch processed at one time. It was pathetic.
The real issue is this: Nikon is a camera maker and a lens maker, and it has verrrry little reason to hire the kind of software engineers and developers and support staff that is needed in the MODERN software business. Adobe is an example of a ***software company***, which has every reason to offer the exact kind of services, products, and support that is needed to make good **software**.
I would say, make your life EASIER, and quit fighting the crappy software that Nikon has become infamous for.
