"Unable to access Sentinel Run-time environment (H0033)" error occurs when launching e4 software.
It is most likely caused by antivirus software, in particular, Avast or AVG antivirus software. Avast and AVG can conflict with HASP security, they won't touch installed Wilcom software though. This error still happens after the "Wilcom" folder is added to the Exception list of Avast or AVG. The user has to replace Avast or AVG with another antivirus software.
