Please what can i do if my access to run my code on code blocks is being denied.

Answer 1

you probably need to make sure that your program is no longer running, if thats the case you need to either kill it or give it a new name.

Answer 2

I don't understand what you mean by kill it please

Answer 3

close the version of your program you have already running. look for it on the task manager and end the process
