Please take a screen shot of this and send it to icomancer_support@lavasoftworks.com so we can figure out how to fix it.

Either icomancer isn't recognizing characters in the path you want to set the icon to or something is messing with icomancer reading the path.

Please try running icomancer as administrator and then setting the icon to the folder. If after this, the problem persists, please let me know.
