How to get the install Scripts of NSIS installer self?

I want to get the .nsi scripts of NSIS self setup.

version2.07 or 2.08 ,both ok.

Only for study.

How?


Today I installed NSIS v2.08,it can detect other version installed on my OS,and then show a "installed" page let me select to uninstall old version.

I want my own installer like this.

Thanks.

The script is already in your Examples directory, named makensis.nsi. If you don't have that directory in your NSIS installation folder, reinstall with "Script Examples".

Yeah, I used the same thing on my installers.

Now OK,thanks a lot.
