Windows 7: Allow non-admin users install .msi in Windows 7 Professional

Hi, I need configure Windows 7 Professional to perform:

- Allow non-admin users install (and update) a .msi file.

I tried creating thie key AlwaysInstallElevated , set = 1, in the registry:

HKEY_CURRENT_USER \Software \Policies \Microsoft \Windows \Installer
HKEY_LOCAL_MACHINE \Software \Policies \Microsoft \Windows \Installer

But didn't work, also, the key (Installer) don't exist, I creat it.

I also tried create rules in the AppLock, with Hash and Path parameters, but didn't work, and the Documentation says that Win 7 can create rules, but can't apply them, only Windows 7 Ultimate and Enterprise.
