Do not load an asset file on Desktop. Why ?

Hi.
I loaded an asset file in unity3d tool.

And I did build it to PC platform and make exe file.
But i clicked the exe file, can not see anything.

Why ? If you know it, let me know ASAP.
Thanks.

an asset’s path : const string url = “file://e:\down\como_open.unity3d”;

If you want to load things at runtime, I would suggest using the resources class

What does your log file say?
