Different RequestExecutionLevel for installer and uninstaller
Is it possible to have RequestExecutionLevel user for the installer but having an uninstaller with RequestExecutionLevel highest? If yes, how?

Thanks,
Yves

What you are asking does not really make sense, but to do it, you have to compile the uninstaller externally (by !system etc) and include it in your installer as a .exe

My problem is that if I have RequestExecutionLevel highest set, then i cannot build automatically from vista/7 wihtout clicking ok while extracting the uninstaller before building... :-( I need a workaround for that!

why do you need to extract the uninstaller before building?
in order to sign it?
then this means you build your .NSI twice?
then you could use a /D command-line switch so that the first time (when you really only want the uninstaller) the RequestExecutionLevel is different

If I launch the installer with RequestExecutionLevel user to extract the uninstaller than the uninstaller will run with that level as well afaik. :-(

use the procedure explained here:
http://nsis.sourceforge.net/Signing_an_Uninstaller
and a /D NSIS command-line
to create the uninstaller separatedly (with RequestExecutionLevel highest), and embed it in your "user" installer

When I create the uninstaller with RequestExecutionLevel highest I cannot build automatically as described before. Windows Vista/7 requests confirmation for the UAC change...

create the uninstaller with RequestExecutionLevel highest
THEN
create the installer with RequestExecutionLevel user and embed the previous uninstaller (with File, rather than WriteUninstaller)

like in the procedure http://nsis.sourceforge.net/Signing_an_Uninstaller
