Yes tried fresh. iVMS-4200(V3.11.0.5_E). And also tried older versions.
Tried many times to install and uninstall. And tried with specific uninstallers to clean everything what is ivms4200, from system disk and from registry.
Tried with admin privileges.
Windows 10. OS build 19045.4355 , no more updates available.
Also tried sfc /scannow , and all sorts of DISM commands to repair system.
I'm thinking maybe this new version 3.11... and etc., upgraded older version (3.8...) not like it suppose to, and left something somewhere, or removed something somewhere what it was not suppose to.
