sen2cor outputs are classed as "invalid rasters" by ArcGIS

I’m running windows 8 and have followed the sen2cor 2.1.1 installation instructions. Everything runs fine but the outputs are classed as “invalid rasters” by ArcGIS 10.4

I was running sen2cor (–resolution=10) on a Granule and have checked all the input rasters (all load fine in ArcGIS). The outputs are the 20m and 10m images.

I’ve checked all the outputs and the only one that works is:
S2A_USER_SCL_L2A_TL_EPA__20160419T085223_A000890_T35LPC_20m.jp2

Attached is a screenshot of the output folder structure

Just to update it looks like a problem with Arc rather than sen2cor. They load fine in QGIS
