(Un)installer icon problems
Hi,

I've created an installer and an uninstaller icon for an application I'm working on. NSIS won't compile my installer though, because of "icon size mismatch". I have read, that this applies to the actual icons, their resolutions etc., not necessarily the disk space the ico files use. Is this true?

My ico files each contain icons with the following properties:
256x256x32
128x128x32
48x48x32
32x32x32
24x24x32
16x16x32

They're in the same order. The actual ico files are of different sizes (in terms of bytes).

What can I do to make NSIS accept these icons?

Thanks,
Dethread

P.S.: Here the ico files, maybe someone can spot what's wrong?
install.ico
uninstall.ico

my icon editor claims they are invalid icons, yet xp displays them

Thanks for taking a look. I created those icons with IconWorkshop 6.0.1. The 256x256 icon is supposed to be for Vista (the program claims). After deleting that NSIS took it just fine.

I just found the actual problem:
IconWorkshop can compress the 256x256 icon internally. This compression is what must have cause different sizes. After deactivating that option, NSIS took the icons just fine.

yeah, the bigger icons can be PNG in vista to save space
