You can only install if you have admin rights

--------------
Windows Vista

Hi

What is the best approach to inform the user that they can only install our product providing they have admin rights.

Is there a way to raise the administrator dialog in Vista.

Regards

UserInfo plugin (part of nsis) and MessageBox or Custom Page

for vista, use RequestExecutionLevel admin (this only works when UAC is on) If you need to support 2k/XP or Vista with UAC off, check if the user is admin with UserInfo and display a dialog and quit if they are not, or use the UAC plugin

Hi

I have a problem that occurs that I cannot reproduce.

Current setup is:
Windows Vista
Amin rights
UAC is on

When the installer is double clicked the installer dialog appears. Everything is fine until the installer starts copying files over to Program files. The installer errors on the very first file transfer and displays a message that is not helpful to the user and I can't remember what is said anyway :-/

The reason is that the user does not have admin rights when in fact they do, this is due to UAC I think. So they simply run the installer with admin rights (right-clicking the installer and run as admin).

My question is:

Why does Windows allow the installer to get that far and then the moment we start to copy files over the installer errors.

What can I do to get around this problem?

Cheers

Paul

if you have "RequestExecutionLevel admin" in your script, the elevation dialog should pop up right away, if it does not, you should file a bug report

In Function .onInit, insert:
;Does user have Admin privileges?
Push $R0
Call IsUserAdmin
Pop $R0
${If} $R0 == "false"
MessageBox MB_OK|MB_ICONEXCLAMATION "This installer must be run with Administrative Privileges"
Abort
${EndIf}
