I used to get that error about 32 bits per pixel too. I remember at one point I installed libtiff and I also started using the tessnet2 interface from Remi Thomas of this discussion group. It works well with C# in a .Net environment and will handle the bmp files and doing what it takes to make tesseract happy. I believe if you view his profile you will find mention of tessnet2. (I am not sure whether it was libtiff or tessnet2 that made the difference, but in general tesseract is said not to directly support color files, such as 32 bits per pixel, but with libtiff and tessnet2 it seems to work for me. Hope it works for you too. :)
