Hi b34ny,
Is this on Windows 10 v1703? There is a known issue with our DLL injection in certain dllhost.exe processes, and you can use the DirectFlex blacklist feature to address this.
To configure this, create a Blacklist.xml file in the ...\General\FlexRepository\DirectFlex folder (which does not exist by default), with the following content:
<?xml version='1.0' encoding='utf-8'?>
<userEnvironmentSettings>
<setting type='blacklist' list='dllhost.exe'/>
</userEnvironmentSettings>
If you already have this Blacklist.xml file, just update its list attribute by adding |dllhost.exe at the end of the current value (note the '|' (pipe character), which acts as a separator).
The next release of UEM will address this issue.
