Stop & Go

Hi all

I want to do to my own installer exactly the same that NSIS 2.25 installer do detecting that another previous version is installed and asking to unistall first and do it, and continue installation

How can i do that?
I think the eky is reading the registry and running the old unistaller, Im right??

TIA

Check out the source code of the NSIS installer in Examples\makensis.nsi. The PageReinstall function is where the magic happens.

Great Kichik, this makensis.nsi is newer in the examples folder no?, because i never see before

Thanks again

It has been there forever 😉

Ups... Im blind
