Updating the Website virtual directory (MSI -Installshield)

I am using InstallShield 2010 I am trying to create an installatio开发者_如何学JAVAn MSI which will modify a Web application's virtual directory path under the "Default Web Site". I was trying many way in the Installation Designer but I can't mange to overwrite the changes. It is possible to do it or do I need to implement custom actions.

Thanks Thurein

Are you trying to update the root directory of the default website itself? ( I.E. change it from C:\InetPub to something else ) If so, InstallShield doesn't support this. You can create additional virtual directories and you can create additional websites responding on different ip's, ports or host headers but you can't update the root default website out of concern of messing up existing applications and content.
