Runescape is installed on my kali build but will not launch

I am trying to install and run runescape into my kali build. I have “successfully” installed all dependencies and have run the instructions to install from the official site. It is listed in my app menu but when i click it, nothing launches. I have a feeling it has to do with root privileges. If not, any help would be much appreciated. I am a new user so i can only add the screenshot as they allow. it is simply a picture of runescape in my app menu.

libmwmclmcr.so cannot locate libXp.so.6 while it is installed

I tried to run a compiled matlab code which gave me the following error:

.....libmwmclmcr.so Error: libXp.so.6: cannot open shared object file: No such file or directory 

I found here that newer versions of ubuntu don’t have libXp.so.6, so I decided to install it from here. To check this I ran locate libXp.so.6 giving me:

/usr/lib/i386-linux-gnu/libXp.so.6 /usr/lib/i386-linux-gnu/libXp.so.6.2.0 

This seemed to look good, however when I run the code again I still have the same error. Similarly when I call ldd /home/rick/Desktop/tico/tico/v74/bin/glnx86/libmwmclmcr.so:

..... libXp.so.6 => not found libXt.so.6 => not found libXp.so.6 => not found libXt.so.6 => not found libXt.so.6 => not found libSM.so.6 => not found libICE.so.6 => not found libXp.so.6 => not found ..... 

I can’t figure out why it is installed but libmwmclmcr.so cannot locate it?

I have Visual Studio 2019 and have installed all the developer kits/targeting frameworks looking to use .Net 4.6.1 but have issues

I have Visual Studio 2019 and have installed all the developer kits/targeting frameworks looking to use .Net 4.6.1 for entity framework 6.2.0 but when I go to the project properties I do not see anything besides .Net Core 2.2 in the targeting frameworks? I could use some help figuring out what I am doing wrong.

I installed ELK on my server, but I do not know used some documentation commands

I installed ELK on my server, but I do not know used some documentation commands.

I installed ELK 7.1 on Ubuntu 18.04 :

$   wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add - $   echo "deb https://artifacts.elastic.co/packages/7.x/apt stable main" | sudo tee -a /etc/apt/sources.list.d/elastic-7.x.list 

In the documentation there are commands to generate the SSL certificate. But it does not work for Ubuntu 18.04 :

https://www.elastic.co/guide/en/elasticsearch/reference/current/certutil.html

bin/elasticsearch-certutil cert -out config/elastic-certificates.p12 -pass "" 

What is the equivalent for my installation ?
