How to use the UAC Plugin ?

Hi everyone, first of all I'll ask you to excuse my English (yes, I'm French 😉 ).

I've got some troubles to make the UAC Plugin working...

I've read the following page : http://nsis.sourceforge.net/UAC_plug-in

And after having downloaded the zip file and read the examples given in it, I compiled them but none succeeded...

Then I just tried to insert the code given in the page in my .nsi :
First :
RequestExecutionLevel user
at the beginning of the script,

Then 
!include 'UAC.nsh'
And to finish 
; Attempt to give the UAC plug-in a user process and an admin process.
Function .OnInit
 
UAC_Elevate:
    UAC::RunElevated 
    StrCmp 1223 $0 UAC_ElevationAborted ; UAC dialog aborted by user?
    StrCmp 0 $0 0 UAC_Err ; Error?
    StrCmp 1 $1 0 UAC_Success ;Are we the real deal or just the wrapper?
    Quit
 
UAC_Err:
    MessageBox mb_iconstop "Unable to elevate, error $0"
    Abort
 
UAC_ElevationAborted:
    # elevation was aborted, run as normal?
    MessageBox mb_iconstop "This installer requires admin access, aborting!"
    Abort
 
UAC_Success:
    StrCmp 1 $3 +4 ;Admin?
    StrCmp 3 $1 0 UAC_ElevationAborted ;Try again?
    MessageBox mb_iconstop "This installer requires admin access, try again"
    goto UAC_Elevate 
 
FunctionEnd
with my own functions.

But when I try to compile, I've got the following error :

Function: ".OnInit"
Invalid command: UAC::RunElevated
Error in script "C:\Users\Me\MyFolder\MyScript.nsi" on line 156 -- aborting creation process

I think I've missed something, the file UAC.nsh is in the same directory as the script (MyFolder).

Can anybody try to help me please ? 😢

Put UAC.dll in the Plugins folder.

Hi

In the package there's actually two UAC.dll, one in a A/ directory and one in U/.
I put the A one in Plugins (for no worthwhile reason) and when the installer asks for elevation it does so with a weird (random/temp) name. Should I have used the one in U/ (and does anyone know what the difference is ?)
Anders#
A=ansi (normal official nsis)
U=unicode (3rd party nsis version)

The installer command should look something like: c:\path\installer.exe /UAC:1234 /NCRC

The uninstaller on the other hand might be in %temp% and have a weird name, but thats how NSIS does it
