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!

Here's the link to the picture

Another option is to open the PNG or other format with Paint (may need to be downloaded from Store in the latest Windows versions) and save it as BMP. It will automatically select 24-bit depth and other settings will be compatible.

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)

I have been able to circumvent this problem by taking a screen capture of my bitmap image, opening a graphic editor, pasting the screen cap and cropping it back to the original size, then saving it as a new bitmap image.

The images I create on my Mac with Pixelmator have this problem. If I used Photoshop 6 on Windows I do not have any issues.

That makes me think it's probably related to headers as described in the link Deanna provided, but since I can't find a good way to easily remove headers this screenshot workaround has been the best solution for me.

Edit: Sounds like Pixelmator includes colorspace information in the header, and Photoshop 6 does not. Reading through all the comments I see that Deanna's link to this question solved the problem: do not include colorspace info when exporting.

Edit: I've also been able to circumvent the problem by opening the file in preview, pressing save, overwriting the original bmp file, and recompiling the setup. Easier than the screencap method.
