Did you set correctly the LM_LICENSE_FILE environment variable.
It must be something like
export LM_LICENSE_FILE=1700@YOURMACHINE

Yes. Everything works fine until you install the HASP driver. Then IDL
ignores the environment variable alltogether and only looks locally for a
license file. If I unistall the HASP driver then IDL works as expected
(finding the license file at port@host).

Although my knowledge of this is quite limited, I suspect that this problem
is a limitation in IDL. With older versions of IDL I seem to remember that
you couldn't just set the LM_LICENSE_FILE variable to port@host to access
the license file from the licensing server and instead you had to install a
copy of your license file on every client. It seems that when started, IDL
looks for the HASP driver and if it is found, it behaves like the older
versions of IDL. At least that is the working theory.

I guess I just have to put up with it until 5.6 when, at least according to
rumor, HASP licensing will be dropped altogether.
