Vista and MSI installation files

By default the User Account Control (UAC) that is integral to Microsoft Vista will not allow .msi installation packages to run because they don't have the "admin" flag set, which is required to indicate that "elevated privileges" are needed to run the package. There are 2 ways to get around this, either:

• turn off UAC, then reboot, then install, then turn UAC back on, then reboot again; or
• modify the registry so that a right click on the msi file shows a new option to "Run as Administrator"

Instructions: save this file VISTA MSI Run As Administrator to your Vista pc and open (or right click "Merge") it. You should then be able to right click on any .msi file and install it using Administrator privileges.
