batbox.exe is included in the batch and should be extracted to your %temp% directory during the batch execution. Try running Toggle Tweaker, leave the window with the batbox error open, then open an explorer window and navigate to %temp%. Do you see batbox.exe there?
Where would all the downloaded files be located? (eg. Uninstallers for Cortana and such)
NOTE: To avoid the elevation glitching; use the tool from a folder on the system drive/partition.
