"Nios II software build tools for eclipse" is not openning

Hi, I found the solution in this forum:

https://www.eevblog.com/forum/fpga/quartus-issue-nios-2-software-build-tools-for-eclipse-crashes-on-startup/

the problem was solved by following the document from "Intel": https://www.intel.com/content/altera-www/global/en_us/index/support/support-resources/knowledge-base/tools/2019/why-does-the-nios--ii-not-installed-after-full-installation-of-t.html
The same instructions also included in the <Intel Quartus installation directory>/nios2eds/bin/README

these are the instructions that you will find for Quartus 20.1 lite

QUARTUS ECLIPSE MANUAL INSTALLATION
1. Download CDT 8.8.1 which is Eclipse C/C++ IDE for Mars.2
a. Windows: https://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/mars/2/eclipse-cpp-mars-2-win32-x86_64.zip
b. Linux: https://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/mars/2/eclipse-cpp-mars-2-linux-gtk-x86_64.tar.gz
2. Extract the downloaded file into <Quartus installation directory>/nios2eds/bin. You should see <Quartus installation directory>/nios2eds/bin/eclipse
folder after extraction is done.
3. Rename <Quartus installation directory>/nios2eds/bin/eclipse folder to <Quartus installation directory>/nios2eds/bin/eclipse_nios2
4. Extract <Quartus installation directory>/nios2eds/bin/eclipse_nios2_plugins.zip (or tar.gz for Linux) to
<Quartus installation directory>/nios2eds/bin. The extraction will override files in <Quartus installation directory>/nios2eds/bin/eclipse_nios2.
5. Verify the extraction is done correctly by making sure you see <Quartus installation directory>/nios2eds/bin/eclipse_nios2/plugin_customization.ini file
6. You can now launch Nios2 II SBT for Eclipse via eclipse-nios2.exe
