Why can't nohup see the file?

Question

linux

In the directory I enter:
nohup ./file &
Where file is an executable file, in ls it is displayed in green.
What I'm getting is an error:

nohup: не удалось выполнить команду «./file»: Нет такого файла или каталога

Then I decided to try to run a file of a different extension (nohup.out) in the same directory as the executable file
nohup ./nohup.out &
. To which I get another error, apparently he sees it:

nohup: не удалось выполнить команду «./nohup.out»: Отказано в доступе

The rights on files 775. I am
authorized from root.

Answer 1

Solution found. The file being launched is 32 bit. The system is 64 bit. It was necessary to install 32 bit libraries on Centos.
