Thank you for answer.
I also tried IfAliceFailsTryThis.exe.
But it was same as Alice.exe did.
One thing different is a folder ".alice" created after running IfAliceFailsTryThis.exe.
Two files is in the folder,
aliceHasNotExited.txt and AlicePreferences.xml.
The content in aliceHasNotExited.txt is "Alice has not exited propertly yet."
What's meaning of this?

Heu... and I read http://www.alice.org/bugs/index.html,
But ImgIcon.exe doesn't exist in my computer.
And I don't know what Iomegaware is.
