No!! I threw everything I had at it!! Reinstalled Java, Quartus, Eclipse, nothing! Eclipse won't start as admin even when run from its own folder. When running eclipsec-nios2.exe from the command line (again, as admin), it gives the following message:
Error - failed to launch '"C:/intelfpga_lite/19.1/nios2eds/bin/eclipse_nios2/eclipsec.exe" "-pluginCustomization" "C:/intelfpga_lite/19.1/nios2eds/bin/eclipse_nios2/plugin_customization.ini" "-vm" "C:/intelfpga_lite/19.1/quartus//bin64/jre64/bin/java.exe"
Both files indicated exist. Whatever is happening inside them is failing and I can't figure this out!! Why, Intel, WHY would you use such a shaky platform to build your tools?? I'm going crazy!
Like, literally, what I want to do with my FPGA I have to figure out how to do it in Verilog now. Grrrr!!
YES! It works! I installed Quartus 16.0 just to be sure.
This is why no one wants new, updated software!!
Thanks druva1, we are in this together!!
I am also having this problem with 20.1, it just won't start, it quits immediately. I was trying to upgrade from 18.1. Not sure if it is related but apparently Intel switched from Cygwin to wsl. It tool me an hour to get the nios ii console running, you first have to install wsl, then ubuntu and then several apt-get packages. Only to find out that although the nios console works, eclipse-nios2 still doesn't. This is a real dependency hell.
