Quartus Prime 20.1 LITE Nios Eclipse Not Opening

[WUnkn]

Hi all, I installed Quartus Prime 20.1 LITE on Windows latest build, BUILD 18363.1256

But Nios2 Eclipse will not start, no GUI

I have tried instructions from these posts,

https://community.intel.com/t5/Intel-Quartus-Prime-Software/Nios-2-Eclipse-Not-Opening/m-p/1218611#M66654

https://community.intel.com/t5/Programmable-Devices/Why-Nios-II-cant-open/m-p/1235611#M78141

But, none of them worked.  Please help.  I can down grade to 18.1, but this is my last option

Thank you all,

Thank u.  May I ask if future Quartus Prime release will NOT include Nios2 Eclipse stuff such that user needs to install Eclipse components manually
