Use Wix UI_Advanced Setup

Hello,

I use sharpdevelop to create an MSI installer for my DLL.

Using the minimal setup project I define the installer per user

<RegistryKey Root="HKCU" Key="Software\SWName\Addins\DLLName" Action="createAndRemoveOnUninstall">
                            <RegistryValue Type="string" Value="namespace.className" />
                        </RegistryKey>

or per machine :

<RegistryKey Root="HKLM" Key="Software\SWName\Addins\DLLName" Action="createAndRemoveOnUninstall">
                            <RegistryValue Type="string" Value="namespace.className" />
                        </RegistryKey>

I would like to give the user the option to decide if to install for him or for all users.

I have found it can be done by Wix advanced setup project, but this option is missing in sharpdevelop.

Any idea how to implement this would be highly appreciated.

Thanks in advance!
