Is it possible to install and use Clarity in LTSC Windows 10?
It is not possible to install Clarity on Windows 10 LTSC releases, where .NET Framework version 4.8 or newer cannot be installed (this should apply to Windows 10 Enterprise LTSC 2015). Clarity installation requires .NET Framework version 4.8, introduced as part of Windows updates in 2019 (Windows build 1903).
Importantly, DataApex cannot guarantee complete Clarity functionality in LTSC Windows releases, as they are not among supported OS (only OS with the latest updates is fully supported) and are not properly tested with Clarity.
All Software and Hardware requirements are listed here. You can test whether it is possible to install Clarity to the system by downloading and installing Clarity Demo.
