# execute_process

The latest version of this document lives in the [vcpkg repo](https://github.com/Microsoft/vcpkg/blob/master/maintainers/execute_process.md).

Intercepts all calls to execute_process() inside portfiles and fails when Download Mode
is enabled.

In order to execute a process in Download Mode call `vcpkg_execute_in_download_mode()` instead.
