Issue
I have installed Java and am trying to install NetBeans 11.3 on my Windows 10 but after I ran the exe. installer, an error message popped up:
An unexpected exception happened in thread main java.lang.NoClassDefFoundError java/util/jar/Pack200
Solution
NetBeans have problems with the jdk-14, because I suppose that you have install the jdk-14 so uninstall it and try it with the jdk-13.0.2.
