When building a virtualized application without using the capture way,
the application doesn't crash in the original OS which is windows xp, but would crash under windows 7 x64

I have fully isolated the registry.
But I leave the file system as merged.

The target architecture is any CPU.
I've compressed the payload
and enabled window class isolation

I've tested it under windbg, but still got no ideas why it crashed....
Any help for me please?
Thanks
Jack
