I have a WPF application which runs fine on Windows 7 OS. But the same app crashes on a particular few Windows XP machines.
It runs fine on few windows XP machine. but on a few XP machine it fails to start.
ERROR – Image format is unrecognized.
I know this question has been asked few times. but my problem is i am still not able to figure out as to how to resolve this.
Should I change the .ico used for the application ..
If I remember correctly Windows XP does not support icons larger than
48x48 pixelsand this could be the reason for the crash..icofiles should definitely run on both systems.You can create an icon that support multiple sizes, so if you add 48×48 and for example 256×256 in the same file you should be good. Also be sure to use select a good software to produce the icon when making icons that support multiple sized. I’ve used Greenfish Icon Editor which I think works fine. But there are multitudes of other products for this.
Be sure to read The ICON handbook, section Windows, it contains good info about what icon sizes and bit depths to use.
Other threads on SO supports my belief:
problems with icon image
Which icon sizes should my Windows application's icon include?
