Pipe Nsis installer log to console druing the silent install

Question

Is it posible to pipe Nsis installer log to console druing the silent install. Installer is third party so I can't change it. Thanks in advance.

Answer 1

NSIS is a GUI app and does not really support output to the console.

There are two ways to get console output:

• Recompile NSIS with logging to console turned on (NSIS_CONFIG_LOG_STDOUT)
• Call AllocConsole with the system plugin and print custom output

Both of these require changes to the installer so it can only be done by the author of the installer...
