Re: Vista file permission problem
As Jesper pointed out, any program that you do not elevate through a
"Windows needs your permission to continue" prompt does not get to use your
group membership into administrators [among other restrictions]; non-elevated
programs, therefore, will not be able to access files in ways that you only
have access to through your group membership as an administrator.
As you found out, changing the permissions on the resource to specifically
grant you access will allow non-administrative programs to access that
resource without prompting; however, it is important to note that this will
signifigantly reduce the effectiveness of the Windows Vista security
mechanisms when applied to system folders, such as program files.
