Oracle oci.dll missing when running on MSTest agent
===

I'm trying to get some database related integration tests running on a MSTest test agent. We use c# and an oracle db with devart dotconnect.

Since we need to use indirect mode, I installed devart and an oracle client on the test agent.   

The tests run smoothly when I execute them on my local machine. But when executed on the test agent (remotely), it can't find the client's oci.dll, which is a dependency somewhere:

*System.IO.FileNotFoundException: Can not load Oracle client library oci.dll from home ..*

Now, I have no idea why that happens. I checked the PATH environment variables already, but they seem fine. Any ideas why this works on my machine, but not when deployed to the test agent?


edit: added stacktrace within devart:

    Devart.Data.Oracle.OracleHome.get_ClientVersion()
    Devart.Data.Oracle.aw.a(Boolean A_0, Boolean A_1, OracleHome A_2, Boolean A_3)
