#1249 Error while loading icon - GIMP icon unsupported

[Beep6581]

v3.05

I created an icon in GIMP which works correctly in VB6 (that's from 1998), Windows XP and Windows 10. NSIS fails at loading this icon:

Icon: "images\test_icon.ico"
Error while loading icon from "images\test_icon.ico": can't open file

Icon created using GIMP-2.10.18 using default .ico export options, except I disabled compression.

Using:

!include nsDialogs.nsh
(...)
Icon "images\icon.ico"

[Beep6581]

Same with even a simpler icon, just 3 small layers:

Argh, nevermind! Invalid path. Had to use "..\images\icon.ico"

With the correct path, the icon works correctly.

Issue can be closed as invalid.
