Administrative Install vs Normal Install (Windows Installer)
Could someone tell me why I should use administrative install vs. normal install when installing eg. Adobe Flash Player?
I noticed that this is what Adobe recommends in their administrative guide but I have always just used normal install with no problems.
Does administrative install give you any real benefits or is it just a relic from old days?

This is one of those areas which is confused in Windows Installer.
There are 2 scenarios, in essence: an install using an account with local administrative privileges and an install to an Administrative Installation Point (AIP). The former is - I hope - obvious. The latter is the creation of a point on a network share, from which all installs are conducted.
When creating an AIP, you use the '/a' argument to MSIExec.EXE. You are prompted for a location for the AIP. The MSI then extracts uncompressed copies of the files within the package, along with a revised MSI. You would then use *this* MSI for your deployments.
*In general*, most people use AIPs where packages are to be patched: one creates the AIP, applies patches to the AIP and then deploy the patched package.
