Set silent installer exit code?

How does one set a unique exit code/error level and/or error message when using the silent installer feature? I've already searched and found the following:
* How to set exit errorlevel code
* Error Level when installer ends

Neither threads had clear solutions to this problem. I've tried a bunch of various code trying to abort/quit in .onInit and other custom page functions. None appear to set the dos errorlevel (or if it does, its 9009 which clearly isn't my custom errorlevel).

Basically, I'm passing in a silent install configuration file, parsing it out for the stuff I need, running checks on the data the user provided and then if need be, quit the installer with unique error codes/messages depending what is wrong. I realize while one can display a Messagebox for the error, that sort of defeats the purpose of a "silent installer".

Suggestions?

In the thread you linked, kickik said you can't set your own exit code in NSIS.

Hmmm. Fair enough. To use that, I'd try putting IfSilent into .onGuiEnd or something like that.

.oninstsuccess and .oninstfailed then? Or just at the end of the last section.

I agree and saw it in the manual too, but am unable to actually have it work.

Would you please provide sample code demonstrating it working?

I tried modifying the MUI2 'Basic.nsi' example to return an error code. When I ran it using /S on the command-line it returned the correct error code.

I don't understand your problem; perhaps because you have not supplied enough information? For example: How are you making your installer silent?

I'm making the installer silent via the /S command.

Alright, so taking your basic.nsi example, I modified it to set an error level and it doesn't appear to work. Would you please post your sample code?

code:

C:\Program Files\NSIS\Examples\Modern UI>%errorlevel%
'9009' is not recognized as an internal or external command,
operable program or batch file.

C:\Program Files\NSIS\Examples\Modern UI>Basic.exe /S

C:\Program Files\NSIS\Examples\Modern UI>%errorlevel%

operable program or batch file.

I think I see what the problem is:

'9009' is not recognized as an internal or external command,

code:
test >type silent-demo.bat
@echo off
echo Run 'silent-mui-demo.exe' silently by supplying /S on command line
silent-mui-demo.exe /S
echo 'silent-mui-demo.exe /S' returned %ERRORLEVEL%
echo.

test >silent-demo
Run 'silent-mui-demo.exe' silently by supplying /S on command line
'silent-mui-demo.exe /S' returned 1500

Well heck, that made it easy and my existing code does work after all. Guess my validation was wrong the whole time.

Thanks!
