If you get this error, something deleted the actual delta file, possibly your Anti-Virus. Check if it's off first and then go to the same directory/folder (if deltainstaller.exe is on your desktop, go to your desktop) and find a folder called “Delta”

After you’ve done that, delete the folder and just re-open “deltainstaller.exe”. It should work after!
