If you have been running Fledermaus through a blue dongle and licence combination you will need to update your licence as of 7.8.0 either to a new softlock or a HASP dongle.
If you are moving over to a HASP and you do not have QINSy or Qimera you will need to install the drivers for the dongle. They can be found here at the sentinel website or by copying and pasting the following link https://sentinelcustomer.gemalto.com/sentineldownloads/
Please ensure to download this driver for Windows systems: Sentinel HASP/LDK - Windows GUI Run-time Installer
For OSX and Linux operating systems you will need the same website but please check your configuration before installing the driver.
The driver is also available at the bottom of the download page for all QPS applications.
