Is there a programmatic way to determine if the user has sufficient local rights to update the registry (HKLM\SOFTWARE\MYPRODUCT) and create/modify a local file (C:\Program Files\MyProductDir)?

I've written my own custom installer. I'd like to perform these tests before installation begins, without having to determine if the user is logged in as ADMINISTRATOR.

There's some built-in support for ACL (access control lists) and secruity
descriptors in .NET 2.0, but in .NET 1.1 you have to do it all through
p/invoke (most of the functions you need are in advapi32.dll).
There's also a C# wrapper sample project on GotDotNet.com that makes this a
little easier. Here's the link, but I have to warn you I haven't used it
yet, so I don't make any guarantees about it's stability or usability -
