InstallShiled Activation Wizard has stopped working (2014)

Dear Support,

Our development server with InstallShield 2014 on it died and so we vitalised the backup.

I was trying to reauthorise it using the offline method as the automatic authorisation failed and I couldn't see where to release the licence from the now dead hardware.

When I click on the InstallShield 2014 shortcut now I receive the message
---------------------------
InstallShield
---------------------------
The product license has been corrupted. You must repair the license before you can continue. Click yes to repair now.
---------------------------
Yes No
---------------------------

When I click No nothing happens and when I click Yes I get a crash message "InstallShiled Activation Wizard has stopped working".

1. Is there a way to start in safe mode to reset the activation process?

We have installShield 2013 installed on the same server which activated without issues... manly because the auto activation worked first time.
