How to get the installer path in Inno Setup?

问题:

Do you know the right method to get the installer path in Inno Setup?

I want to catch that value inside the [Code] section.

回答1:

{srcexe} will give you the path and filename of the setup.
{src} will give you just the installer path.

回答2:

You should use the {srcexe} constant. In Pascal scripting, you can obtain the values of constants using the ExpandConstant function, as in

path := ExpandConstant('{srcexe}');
