Strange, the only place where I change the icon is right at the beginning of the app:

Like this: IconSource="/Resources/Logo.ico"

Are you running your Windows at a different color space than 32bits?
I'm going to add some checks to avoid the crash, at least.

Can you test if it opens? This version is just for testing if it opens or not, there's some other broken features, so ignore it.
If it's opening, check if the icon is appearing on your notification area.

It opens without any errors or messages displayed. Goes straight to the startup screen. The notification icon is blank - as in, it appears along side other icons (i noticed the shuffle as it added itself) in the tray notification area, but no icon is showing - just a fully transparent icon or space for where an icon would be.

Running Win7 x64 with full 32bit desktop colors

Thank you. At least it opens now.

Now I need to understand why my icon is not loading.
It's strange because the file is attached to the executable and is the same that appears in the taskbar and in the executable file in the Windows Explorer. I'm assuming that you can see the ScreenToGif icon on your taskbar and in the executable file.

ScreenToGif_Test_2.zip
Here's another with a slightly changed initialization behavior.
If it still does not work, I'll have to export the icon again, exporting as 256 colors too.

Thank you. Same crash, looks like it's the same reason.
It's hard to know exactly what's wrong, specially without having a computer having the same crash.
I added the icon with 256 colors too.

From what I know about this error, it's Windows telling the user that it can't load anything else.
Too many GDI objects were already loaded.

If this issue happens again with you people, can you open Task Manager and go to Details, and right click on the header of the data grid, enable GDI objects and see if there's a process eating too much GDI objects.
