Reporting status to the installer from C code

Hai all,
I am calling a exe from my installation script and what i need is a way to inform the script about the success or failure of the execution file. How can i do this? I tried returning -1,0,1 but it reacts simillar for all the values. Can any one help me please. Thanks a lot.

Use:

ExecWait "app.exe" $R0

$R0 contains return code

But ExecWait will popup command window. That should not happen here. So is there anyother way to get it using nsExec's

nsExec returns it to the stack.

nsExec::ExecToLog "app.exe"
Pop $R0

$R0 contains return value

nsExec::ExecToLog "app.exe"
Pop $R0

If $R0 is "" then it was a success.


You could do...

StrCmp $R0 "" 0 Skip #checks if execution was success or failure

---Stuff here---

Skip: #skips stuff to do
