You've probably got a 24-bit uncompressed bitmap. I use 8-bit compressed bitmaps for all my installers, generally around 1/10th the size with negligible difference in quality.
It's limitation of Windows Installer, not a limitation of WiX. See http://msdn.microsoft.com/en-us/library/aa367830(VS.85).aspx for more information. To convert a 24-bit uncompressed bitmap to an 8-bit compressed bitmap in Photoshop simply do the following: 1) Open up your bitmap 2) Convert to indexed color (Image > Mode > Indexed) 3) Do a "Save As", name your file 4) Now on the options dialog that pops up select "Compressed (RLE)" checkbox Good luck :) Sascha On Tue, Aug 25, 2009 at 3:03 PM, Sebastian Brand (Instyler Software)<wix+us...@instyler.com> wrote: > Hi Sebastiaan, > > Windows Installer only supports BMP and JPG, and I remember the built- > in reszing method looks horrible too.
