Hi Everyone,
I'm having a problem creating my own boot screen for my vista computer. It's saying that I'm not the computers administrator but when I go to my user accounts it says that I am the computers administrator. Every time I try and Load a boot screen it says that it's unable to save the boot screen file. An error accord while generating the boot screen file. This is usually caused by insufficient security privileges. Try running this application under the administrators account. I hope someone can help me.
Thank you, sunnie
