How to get Administrator previleges during Installation with custom action

hi, i have build .net form application which requires Java Runtime Environment (JRE)
i'm trying to create an installer which will do some actions as described below

- install the Java Runtime Environment (JRE)
- copy some file to the JRE installed folder.

my issues are

if the client has no administrator privilege, the client needs to right click the installer and select the run as menu and enter the administrator username and password right? now how can i get the username and password to be used in the custom action?? because i need them to install the JRE and do the copy thing.

or any other way to achieve this?

regards, Tris Setiawan.

Hi Tris Setiawan,

Welcome to MSDN.

First I wonder why your .net application need Java Runtime Environment?

Second, once you right click the setup file to run as administrator, your code will have administrator privilege to do some action such as copying files to a special folder. But since MSI does not allow to start another process during installation, so the installer won’t allow you to install JRE.

If I misunderstood your meaning, please feel free to tell me.

You can't get hold of somebody's password, so you can't do this. What problem are you trying to solve? Why do you need somebody else's password?

I havethe same issue. because we have quite often customized file other than executation file, like customer image or template. the execute file is quite stable, two three months a new release.I create a custom action in msi file. the custom action xcopy some setting and customized file into install folder under programm file. which works fine in XP. but in vista and windows 7, we find that xcopy fail to work if not running as adminstrator.
is it possible to take the administrator right to the custom action in msi. or I need to write a DLL instead of directly use xcopy?

thanks.
