Writing to HKLM in Vista

Hello everyone,

i try writing to HKLM\Software\...... with one of my installers, i have defined

RequestExecutionLevel admin

but it does not work, UAC is disabled on my machine.

Anyone know a quick workaround?

Btw. here is what i use to test

; example1.nsi

;

; This script is perhaps one of the simplest NSIs you can make. All of the

; optional settings are left to their default settings. The installer simply 

; prompts the user asking them where to install, and drops a copy of example1.nsi

; there. 



;--------------------------------



; The name of the installer

Name "Example1"



; The file to write

OutFile "example1.exe"



; The default installation directory

InstallDir $DESKTOP\Example1



; Request application privileges for Windows Vista

RequestExecutionLevel admin



;--------------------------------



; Pages



Page directory

Page instfiles



;--------------------------------



; The stuff to install

Section "" ;No components page, name is not important



  ; Set output path to the installation directory.

  SetOutPath $INSTDIR

  

  ; Put file there

  File example1.nsi



  WriteRegStr HKLM "Software\My Company\My Software" "String Value" "dead beef"



  

SectionEnd ; end the section

Thanks in advance

Call IsUserAdmin in your .onInit.

Well just so i can say i have done it, i have done that, it confirmed that the logged on user is an Administrator, but it still cannot write to HKLM\Software.....

Any other ideas?

This is a bug in vista, when UAC is off and you are running as non-admin, elevation does not work. So you can check in oninit and display a message, or you can use the UAC plugin to elevate, it has built in manual elevation to work around this bug

UAC is off but I AM an admin.

Do you have in your sections the following?

SetShellVarContext all

Do you have in your sections the following? quote:SetShellVarContext all

for writing to the registry ?

If you are admin, nothing should be stopping you from writing to HKLM, you could try Process Monitor from sysinternals and see if it gives you any clues (ERROR_ACCESS_DENIED etc)

Wow, thanks for the tip, i now know where it writes my entries, it seems since i am on a Vista 64-bit Machine that it "reflects" registry entries from 32-bit apps to:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\My Company\My Software

and here MS says why:



Nice to know, but that redirector seems to work, at least it reads from there also without any manual intervention.

SetRegView might be of help
