I'm getting a weird exception when trying to initialize NLog instance as a static class member (update: this is happening in a desktop app which is targeting .NET 4.0).
The problem is, I'm getting it only on one specific client machine, and can't reproduce on any of my development configurations. Can someone point me in a direction, what should I look for?
PS: User tried to run the app with administrator rights as well, getting same exception.

NLog is instantiated this way (static field on a class):
private static NLog.Logger _logger = NLog.LogManager.GetCurrentClassLogger();
