Modem software install problem

Did an update to Ubuntu 16.04LTS yesterday unfortunately now Ubuntu is giving the messages:

Optus 4G Mobile” contains software intended to be automatically started. Would you like to run it?

and

Oops! There was a problem running this software. Unable to locate program.

Have used terminal to enter as root, navigated to the linux_mbb_install directory i.e. Optus 4G Mobile/linux_mbb_install/ but entering and executing install does not do what is required.

Any suggestions?

Optus E3372 4G USB modem has:
