is NSIS capable of creating a log?

Hello!

I was wondering if NSIS creates a log about install data after compiling
and is there a way how you do it?

I just use HM NIS Edit, so I wasn't clearly sure
how to do it even after reading a help file.

Thank you and have a great day.

If however what you wanted a HM NSIS (makensis) build log, look at the menu and see if "View - LogBox (F8)" is swicthed on.

Then after a build you can right click on the log and choose "save as..."


And I can also advise you to read about makensis in the documentation.
