There has been an increase in problems with Hasp drivers with a Windows update.
At this stage it appears that Microsoft has issued a Windows Update that invalidates the USB driver that Leapfrog installs as part of the application install process. We believe this is in response to the recently released HASP Sentinel emulator.
In order to solve the problem a user will need to uninstall the previous installed drivers and install the most recent HASP Sentinel driver.
Below are the instructions that will resolve the issue:
1. Close Leapfrog and remove the dongle if you have it in.
2. Uninstall Sentinel:
b. Pick Sentinel HA SP/LDK - Command Line Run-time Installer, see the attached image of what to attach
c. Run the installer
d. From Administrator command prompt run:
haspdinst.exe -r -purge
3. Re-install Sentinel driver.
a. Download the new driver: https://sentinel.gemalto.com/support-downloads/sentinel-drivers/
b. Run and install the file.
c. When it has completed, restart Leapfrog. When prompted, plug in the dongle and wait for it to be recognised.
If none of the above works, please shut down the antivirus program before reinstalling the dongle drivers, and see if that works.
If these work arounds fail, please contact support to have this problem escalated.
