AutoCAD version 2017 dropped support for the "transparent" RGB color 192/192/192 in BMP files. You need to use true transparent PNG bitmaps for your custom icons.

You can batch-convert your existing BMP icon files to transparent PNG files using the IrfanView viewer (free) or any other bitmap editor. Use the following command line to convert the BMP with IrfanView:

"C:\Program Files (x86)\IrfanView\i_view32.exe" MyIcon.BMP /transpcolor=(192,192,192) /convert MyIcon.PNG

You can even leave the original icon names in your .cuix file - any PNG-format picture file renamed to the .BMP extension will load smoothly into your AutoCAD 2017 ribbon.
