return value from the installer exe
 

Hi All,

I have a updater exe written in NSIS. I call this from a VC application using create process.

My design was updater.exe will return a value depending on success or failure or some other condition.

So i tried in .onInstSuccess and .onInstFailed pushing a value to stack and i was thinking this will be a return value of the executable. So i had my VC caller doing a check by

GetExitCodeProcess(pi.hProcess,&dwExitCode)

But i observed that i get exitcode as 0 always or 2 when i call abort in code.

I tried doing
System::Call 'kernel32::ExitProcess(i 5)' to return 5 and close the updater. But doing this crashes the updater as it is being considered as abnormal termination.

So someone advice me, how i can implement my design.

thanks

SetErrorLevel 5

right before your updater exits? Does that work?
