my problem (in those days) was that I did not see the template in my VisualStudio 2017 (all examples were obsolete).
But you can see the template, so this step works and is ok, right?
But If you want to create a new template, you get errors? More details please.
Please see my workflow:
1.) Create Template
2.) Then this wizard starts...
Does this work on your machine?
If not: Then it seems that your wizard-files are broken or some settings are wrong.
With the help of @JimB I found my error.
Maybe you find the bug in your setup with these screenshots.
One last comment to all this stuff:
OpenNX is the wrong description. There are at least 3 kinds of licences. What I mean: It is not "open".
Quite everything is behind a paywall.
I have one advice to all high-level developers: Start with journals.
I just refer to the admin: Learn to use Journal files
FYI - I tried the same thing a few NX versions ago (NX8.5?). I upgraded ALL our NX programs to 8.5 (we have a bunch) in the latest Visual Studio. Seemed to work fine.... until some programs would randomly crash NX! When walking it through the debugger, the crash would occur when a method was returning.
GTAC and I finally realized I should have used the certified version of Visual Studio.
We wasted a lot of time recompiling yet again.
