Problem:
The KEPServerEX 5.19 installation fails when hardware key is selected.

Possible Cause:
Installation with a hardware key on 32-bit Windows 10 was attempted.
While Windows 10 is supported for most configurations, hardware keys are not supported on 32-bit Windows 10 machines.

Solution:

• Install 5.19 with a software license.
  
• Install 5.19 with a hardware key on 64-bit Windows 10 system or Windows 7 system.
  
• Cancel the installation and remain on version 5.18.
