Only had a quick look so what follows is untested and and only really a guess. I have no idea if they will help or how they could compromise the Systems Security.
Open the Local Group Policy Editor by typing gpedit.msc in the Start Menu.
In the right window click Computer Config -> Administrative Templates -> Windows Components -> Windows Installer.
Now here is 3 things you can look at:
- Enable user to patch elevated products
- Enable user control over installs
- Always install with elevated privileges
Always read the description/help, last one comes with a caution.
