How can I run .msi installer with administrator rights?

Question

As in topic. I want to run .msi installer but I cannot install a program because it requires administrator rights. As for .exe files I know how to do that.

EDIT:
My problem is that I don't have 'Run as the administrator' when i righ-click, shift-click, control-click or anything. On .exe files I can see that option but not with .msi.

Answer 2

Right click, Run as. Administrator -Easy as pie. By right windows SHOULD recognise its an installer and kick up UAC tho

Answer 3

I believe you need to hold shift then right click on the msi (or application) to get the 'Run as Administrator' option. As detailed here: http://mockbox.net/windows-7/235-windows-7-run-program-as-a-different-user.html
