VTune reports Haswell server as unsupported architecture

We are able to perform basic sampling under Windows 2012 on an E5-2699 v3 Haswell server. When we try to set up a General Exploration analysis it displays the window for a fraction of a second where it is determining architecture, then reports "unsupported architecture." If we start the VTune run, it quits immediately. Amplifier XE 2015 build 367959, Evaluation installation
Execution engine is CPlex. We don't expect to view source code, simply hoping to evaluate whether cache behavior is a bottleneck.
