When a user attempts to run launcher90 on HP UNIX console, the following error occurs:

Application initialization failed: this isn't a Tk applicationcouldn't connect to display "machine1:0.0"

The ANSYS Launcher could not be started.

The most likely reason is that your DISPLAY environment
variable is either not set (i.e. issue setenv DISPLAY
dev:0.0 where dev is your device name) or is set to a
device that is not accepting the connection.

Why does this error occur?

This error will only happen when DISPLAY={hostname}:0.0 and the current hostname is not enabled in the access control list.
This error will occur when attempting to run any of the wish-based ANSYS applications (launcher, ans_admin, anslic_admin, etc...).
This error is actually caused by a bad HP libxnet library. HP has been notified and will hopefully add the fix to a future patch.

Set the DISPLAY to :0.0 instead of {hostname}:0.0
Enable access control for the current host: "xhost machine1" where machine1 is your current machine's hostname.
