uxe auto installer? where did you find that at? in the usual places? if so what dir?
also, there should be a package that has just the uxe exploit files in it (not an installer). I would use that and place those files in the ude folder. if the auto installer can be extracted, try extracting it and place the files from it into the ude folder.
how do you extract an installer? easy. most installers (like drivers for example) do have an ability to be extracted by using a command switch. here are some examples to try(setup.exe is the name I will use. replace it with whatever the name of the exe is that you are useing).....
run these through a command prompt to make the process easer (click on start, goto run, type "cmd" (without the quotes), navigate to the place that you have the file at, "cd C:\xboxfiles\stuff" and then run the commands)
