Permission denied while executing batch

Hi, I’m trying to execute the MCP’s decompile.bat file using gradle exec: https://hasteb.in/raquwide.gradle
But I receive a permission error: https://hasteb.in/irixucot
This error doesn’t occur when I execute the decompile.bat file directly. Can you help me ?

EDIT: I also tried using Java ProcessBuilder: same error. I also tried to start IDEA in admin mode.

Anyone ?
I still unsolved my problem
