How to upgrade a VB6 application from XP to Vista?

Question

I am working on a vb6 application that has problems with Vista, for obvious reasons (writing to program files and other things that are no longer allowed by default).

• Where should I store application data or user-saved files?
• Do I need to create privileges to create folders and files?
• What other common actions will cause problems?
• The program has an update program that should download and register files, how can I increase privileges in doing so?

Some of these questions have obvious answers, but I want to get the obvious things right.
