Inno Setup Invalid Bitmap Image

I'm trying to replace the sidebar image on the start page of my installer. I keep getting the error 'Bitmap image is not valid'. The specs match the default Inno Setup installer sidebar .bmp exactly. The image I'm trying to use has dimensions of 164 x 314 and has a bit depth of 8 which is what the documentation recommends.

Is there something I'm missing? Any tips are appreciated!

If you are making a BMP from within GIMP and are exporting to a BMP, use the following options:

  • Compatibility Options -> Do not write color space information
  • Advanced Options -> 24 bits (R8 G8 B8)
