Programs aren't blocked. If the application was installed in some other
user account, since most applications were not designed for a multi-user
environment, you usually need to install that application in your own
account as well in order to gain access. If your account is a limited
account, it will have to be changed to an administrator account for the
purpose of installation but can be returned to a limited account status once
installation is complete.
If this does not describe your issue, you will need to be more specific and
tell us exactly what is going on, any error messages and what you would like
to do.
