[netCDF #BDU-355579]: netCDF 4.8.1

Hi,

We do not have the previous version archived, unfortunately.  I could try to 
regenerate them, but I do not currently have the proper environment set up.  I 
think it will be better if we are able to determine why this is happening, as 
it appears to be an issue rooted in Windows and not the installer package 
itself.

Looking into it, it appears that the maximum length of the path is 260 
characters (by default). Source: 
https://docs.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation?tabs=cmd

The same webpage gives instructions to enable Long Paths in Windows 10, but 
this requires editing the registry.  If this is something you're comfortable 
doing, that may be the most immediate solution to this issue. If you're 
uncertain, I would caution you to make sure you know what you're doing, as 
editing the registry improperly can cause serious issues.  In either case, that 
bit of information I've provided is not advice, just information, proceed with 
your own level of comfort!

We can test whether the system path limitation is the issue pretty easily.  
What happens if you try to install it to the root of the C:\ drive? If that 
succeeds, then we know it is probably character path issue inherent to Windows, 
and switching to a different installer won't solve the broader problem.  If it 
still fails with the same issue, we'll know an error (as-of-yet unreported 
before this) has crept in and will need to be addressed with our installer.  

Give installing to the root of C: a try; it's not a great location and can be 
immediately uninstalled, we just want to see if things work properly.  Let us 
know what the result is, and we can figure out how to proceed from there, 
thanks!
