Important Notes
Carl Zeiss Microscopy ZEN Hardware (HASP) Dongle Update for Windows 10 Update 2004 (July 2020)
The Hardware (HASP) Dongle Update for Windows 10 Update 2004 fixes the following problems:

The existing version of the HASP Dongle driver prevents either a Windows 10 update to version 2004 or crashes Windows 10 version 2004 when ZEN blue 3.2 (DVD 85) or ZEN black 3.0 SR (DVD 86) or ZEN black 3.1 LS (DVD 87) or ZEN core v3.0 (DVD 83) is installed after the upgrade to Windows 10 version 2004.

Details: Late May Microsoft started to roll out Windows 10 Version 2004 to consumers that causes this problem. Information from Microsoft on that issue (Issues updating or starting up devices when aksfridge.sys or aksdf.sys is present):

Microsoft stopped deployment of Windows 10 Version 2004 to consumers that have the driver version is question. However, in case a consumer has a brand new computer with a brand new operating system, he most likely will have the problems described.

Installation instructions for latest dongle driver:

Unzip the file HASPDongleDriverUpdate1.zip to a temporary folder and run the batch file. The installation will request administrative privileges to install the driver.
