Why can I not load MrSID files any more into my projects after loading ArCMap 10.4? I've been through the help files and they say to make sure I have the supported raster dataset file formats checked by going to:
Customize > ArcMap Options > Raster > File Formats I have checked that and MrSID files are checked. I even tried re-downloading another copy of the SID files and it still does not work. I have not encountered this problem with prior versions of ArcMap. The errors I recieve when trying to load a SID file are "Invalid raster dataset. Failed to create raster layer." and also "A selected item could not be added to the map. Failed to open raster dataset." Very frustrating.
