I'm still running my production system with Windows 7-Pro, but have a test weather software system with Windows 10-Pro.
I tried to run VWS 15p03, and received an error message (attached) -- VWS wouldn't start.
I contacted Ed and he said
Just delete the file c:\vws\WININET.dll and restart
so I renamed WININET.dll to old-WININET.dll, then VWS would start and work again. This may only happen with folks who have older installations of VWS and have updated them over the years, but it's something to be aware of.
