Obviously sicon.pl isn't an .ico file

Looking at these results and Win32::GUI::Icon docs, it is now obvious that it doesn't preserve $^E from the 2-3 ways it tries to load the file, so $^E ends up being uninformative

FormatMessage() OTOH assumes 0 means success where as $^E doesn't

Since this program works for me for about a dozen icon files I find in program files

I must assume there is something wrong with your box2.ico

good luck figuring it out :) You might hack on some GUI.xs to insert informative diagnostics, or hit up MSDN for specs regarding icon files so you can compare them to box2.ico ...
