If the folders empty it means youve closed the installer!
Dont close the installer or it will delete all installation files included the rom.
Besides theres no guarantee that this will work tho?
Try empting your temp folder.
Ok, I just started running the ruu.exe and it did create the rom.zip. I haven't ran the ruu.exe completely yet, you will see where I am at from the image below. So, should i get the rom.zip and rename it at this stage?
