Why can't the gui program run as a regular user?

Question

linux

Why can't the gui program run as a regular user? Everything works under root.
cds_root command not found
Error: Unable to find the installation_name in your path.
Please correct this and try again.

Answer 1

Thanks a lot guys! Added environment variable under user.
Then xhost + (from under the root)

Answer 2

Perhaps it simply does not find the executable file, because the path to it is not specified in the path?

Answer 3

user dir/with/program$ ./program
And for any directory: add to .bashrc or similar
export PATH=$PATH:/home/user/path_to_program (folder_where_the_binary is)
