Dear all,

 

Sorry for bothering you. I have some problems when installing the IBM ILOG CPLEX Optimization Studio. My laptop is MacBook Pro with system macOS Catalina 10.15.5.

 

Now, I have downloaded the file "cplex_studio1290-osx.app". Then I changed the permission of this file by using following commands in the Terminal:

 

xiaoxuezhang@Xiaoxues-MBP ~ % cd Downloads 

xiaoxuezhang@Xiaoxues-MBP Downloads % chmod +x cplex_studio1290-osx.app 

xiaoxuezhang@Xiaoxues-MBP Downloads % ./cplex_studio1290-osx.app 

zsh: permission denied: ./cplex_studio1290-osx.app

 

But it shows "Permission denied". Could you help me to install this app?

 

Thank you very much for your help. Sorry again for bothering you.

 

Best regards,

Xiaoxue

Can you do 'ls -l cplex_studio1290-osx.app '? What does that show? Does it show that the file is executable. Does it help to do 'chmod u+x' instead of just 'chmod +x'?

Hi Daniel,

Thank you very much for your help. I tried 'chmod u+x' and 'chmod 777', but it doesn't work. The result is same, i.e., "zsh: permission denied: ./cplex_studio1290-osx.app".  

The response of command 'ls -l cplex_studio1290-osx.app' is the following. 

xiaoxuezhang@Xiaoxues-MBP Downloads % ls -l cplex_studio1290-osx.app 

total 0

Best regards,
