Software

As per our requirement, we need to add certain HKCU Registry entries within the package Opus trusthybridmail printer  I added hkcu registies within the Custom MST and since application has advertised shortcut these registries will populates for all user profiles. When tested for the users, this application prompts for UAC requiring admin credentials to proceed further.

To supress the UAC prompt(Which required for Admin Credential) in user context
 1. Tried creating the shims using ACT
 2. Tried manually giving User permissions to InstallDir.
 3. Added registry entry [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Installer]
"AlwaysInstallElevated"=dword:00000001

But none of the options worked. Please advise a workaround for the same.

I also have another issue related to uninstall, this product does not support for silent uninstallation when tested at our end. We tried fetching the exe responsible for uninstallation and passing the silent uninstall parameters but unfortunately it is not working at all. Please suggest an approach to get this working.
