i click the sandbox button.
i get a message saying i ‘must be logged in as administrator to use the sandbox’

ok, im the only one who uses this computer
and i always log in as admin.

how can i get the sandbox to work?

The sandbox is not capable of and not meant to install programs in it.

When you install a program and get the elevated privileges alert you should allow it not sandbox it.
