How did you create NXP.bmp?

NSIS doesn't accept all BMP variants. I sometimes need to open and save bmp files with Paint in order to be sure it will be a valid BMP file.

Nice. :-) I use Gimp too. I've been unable to create valid BMPs for NSIS using Gimp... – Divide

Well, we all know Windows/NSIS is a little silly - the bitmaps are "valid"! When exporting from Gimp, it worked with the following options: Compatibility Options -> Do not write color space information (ticked). Advanced options: 24 bits R8 G8 B8 (ticked). Gimp is probably sensible and saves 32 bit by default, too much for Windows ;) Additionally, the size of the image I used was 150x57px. – Calyptra
