but the first one (.bin) is working, but please what these numbers and extra like 775 , because it s so difficult for me as first day in linux to remember, is there a simple guide or small explaination about how to run these things
that hasn’t got the execute bit enabled either … run:
chmod 775 ~/Downloads/Xilinx/bin/lin64/xsetup
then try
cd ~/Downloads/Xilinx
then
./xsetup
again.
You’re not going to understand this stuff as a first time user … but then again you won’t need to as it’s rare you’ll
a) need to install software in this manner
and
b) end up with software that the author has screwed up the permissions of
I could attempt to explain it all to you, but believe me you’re unlikely to grasp it yet … that’s for the future 
Linux “permissions” are what keeps your system safe, they’re an integral part of what makes Linux one of (if not the) safest OS out there … but to explain the whole permission system at this point is a big ask.
If you want to know what the
drwxr-x-r-x
mean, along with the 775
this might help

also permission denied
try it with sudo then
cd ~/Downloads/Xilinx
then
sudo ./xsetup
and if it errors, I’ll need the EXACT error in its entirety.

hayder@hayder-Lenovo-G50-80 ~ $ cd ~/Downloads/Xilinx
hayder@hayder-Lenovo-G50-80 ~/Downloads/Xilinx $ ./xsetup
./bin/lin64/xsetup: line 21: /home/hayder/Downloads/Xilinx/bin/lin64/_xsetup: Permission denied

chmod 775 /home/hayder/Downloads/Xilinx/bin/lin64/_xsetup
then
cd /home/hayder/Downloads/Xilinx
then
./xsetup
Whoever packaged this software is an ijit 
What might make things easier is if we give everything in the Xilinx directory 755 permissions recursively … so
chmod -R 755 ~/home/hayder/Downloads/Xilinx
then
cd /home/hayder/Downloads/Xilinx
then
./xsetup
Remember, Linux commands ARE case sensitive, so that’s a capital R in the first command
yessssss, it works
