I have a problem with the EO.WebBrowser for .NET.

For a customer I get an error when starting our application that uses the WebBrowser:

Failed to start image manager

After my research on the internet, I would guess that the cause of the error is that the eowp.exe cannot be started.

The customer uses AppLocker, but has EssentialObjects enabled as the publisher and our application has been working there. Only after updating the application the above error occurs.

The application uses version 21.1.67 of EssentialObjects. The version of eowp.exe, however, is 20.3.34. This file can also be executed via the command line. I get the following output

eowp.exe
This program is a part of EO.Total.

AddMissingAPIModule:dwrite.dll

The following details are output about the error:
