Bug with 4.25.4
There is a known issue with 4.25.4 where it fails to build with an error message: AutomationException: Attempt to add file to temp storage manifest that does not exist (<Path To Engine>\cpp.hint) This issue has been fixed in 4.26 but if you need to use 4.25.4 see this workaround by Bernard Rouhi:

Access Denied on some files?
On Windows, just change the ownership to Users then try again. To change ownership on Windows, follow these steps

  • Right click on the UE4 folder, choose Properties
  • Switch to Security tab
  • Click on Advanced
  • Near the top, click on Change User
  • A new dialog will open, in the text box at bottom, type in "Users", then click Check Names
  • OK till the end.
