I have NSw/BU version 22.5.2.15 installed on a [official] Windows 10 Pro 64-bit [installed over 8.1]. All was working fine.
Today, I received a cumulative update via Windows Update. Since then, NS will not open. I get a brief spinning cursor and then nothing. I have rebooted. I have shut down and restarted. Issue did not resolve.
Interestingly, I can right-click on the taskbar for Live Update, Get Support, etc. and they work. But the program will not open to the main interface [even via the right-click]. IS works in IE, as well.
Weird. Anyone?
