Microsoft’s patches for November have an impact on TSplus compatibility, more specifically on Windows 10 / Windows Server 2019 on both 32 and 64 bits.
The issue occurs with KB4586839.
We are working hard to deploy an automatic and silent kernel update. In the meantime please do not install this update from Microsoft, or if you alreay installed it, uninstall it.
If you have this update on your system it will prevent TSplus to handle the sessions, you will be able only to have 1 or 2 concurrent sessions.
To keep your TSplus installation always up to date it is necessary to subscribe a mantainance subscription. The subscription starts from the date of activation and can be made or renewed for one, two or three years.
