Hi,
By default, all accounts - even an admin - are locked down and do not have
permission to write to or alter designated system folders. This is to
prevent malware from usurping the user's privileges to write to a system
folder or make changes without the user's knowledge. This includes the
Program Files directory. Software designed for Vista runs from a virtual
folder within the user's appdata directory where the user has the right
level of privilege. Software not designed for Vista tries to run from the
Program Files directory, writing to and altering files, where the user does
not have the default level of privilege necessary for those actions. For
this to work, they have to specifically invoke it using 'run as
administrator'.
