Incorrect icon size when imported to exe

EDIT: Solved, (at least for the explorer) the problem was it keeps the old thumbs.db.

I have a png icon and I've created a 128px, 96px, 64px, 32px, 16px icon using several tools. But the result is always the same.. when I compile the exe using that icon and resize to max icon size, it stays to something like 32-48px. Anyone got the same issue? Also when I put the executable on RocketDock, it also gets small icon. The executable has all icons, I checked it with Resource Hacker. It's a strange issue, I just wanted to make my app with big icon so it can be used in dock applications and on users that use bigger icon size开发者_如何转开发s.

Here's an example of what I'm talking about. The Visual Studio icon is there just for test.

And also a RocketDock screenshot containing a shortcut to the icon and to the executable:

I've used Axialis Icon Workshop successfully before, and it's even recommended in this MSDN article. Not free but the trial version should be enough for one-off shots. I'm not perfectly sure it will solve your problem but it should.
