“Program Files” permissions in Vista
Being a new to Vista I ran into a problem that I cannot modify a property file in the “Program Files (x86)” directory even though I’m an administrator and have the ownership of that file. Instead of disabling User Access Control (UAC) I had to run the command prompt with administrator privileges. (“Start” menu, right click on the “Command Prompt”, then “Run as administrator”). From there you can do what you need (e.g. start a notepad and update the file you need to update).
