I have read its Help Document,I found there is a function named "Abort" can terminate the process if it called from "InitializeSetup" or several other procedures.But I guess this is not a secure and normal terminate function.How can I stop an innosetup installation process in a secure and normal way whenever the process is running?

What I have tried:

Read the Help Document and read again again and again.

Hello,

The only way to terminate setup is calling a function that simulates
Cancel click. Currently, you should simply complain by MsgBox in
NextButtonClick event handler if a certain file is not found and return
False (to prevent page from changing).

Taken from: Re: Abort Installation in Code - yet?[^]

Things may have changed since then though, and I think you could probably seek help in InnoSetup's own Newsgroups[^]

PS: I'm not sure why's your query tagged as C++ as it's got nothing to do with C++.

Thanks for you comments,I'm used to tag c++，maybe I should have tagged as pascal or innosetup.I remember that codeproject not support custom tags... Now I found the installation can be stopped in InitializeSetup before anything is installed,maybe there is a way to send close message to the process instead of click the cancelbtn to stop the installation,I haven't tried this method so far...

While you're welcome to post questions here, I personally feel that questions relating specifically to Innosetup will get more attention at Innosetup newsgroups.
