I appear to be having a strange issue, and I'm not sure if it even worked at all. The 7Updater60 (I tried the 57 as well) seems to close instantly the moment I point it to the extracted ISO on the USB stick I'm using. Opening cmd as admin and opening the file itself brings up the error message with something among the lines of ""Can't open E:\sources\boot.wim" read-only: Invalid argument. Exiting with error code 47: failed to open a file. x86_64 was unexpected at the time"
I'm quite certain none of the files are read-only, they're freshly extracted.
I tested this on two Windows 7 computers with the same results. Am I missing a critical step? What's going on?
