Hi,

We have a customer trying to open our application which uses the EO WebBrowser control for WPF.

Unfortunately they cannot get it to launch with an immediate crash to desktop.

The application event log contains 2 errors (see below):

This may be related to the Trend antivirus issue reported elsewhere, however, Trend is not reporting anything when crashing.
Also, our customers have added an exception to exclude our .exe file, so I'm not sure Trend is to blame for this one:

Here are the details of the 2 event log entries - is this something that you've seen before:

Hi,

This exception came from 17.1.30.0. However we only have one user with this particular crash...

We are currently preparing to put out v17.2.0.0. Do you know if this will fix this as a known issue?

Thanks.
