when i packing project it is show this error … what can I do ??
to complete packing 
Looks like that PDB file may be permission locked, unable to be overwritten. I’d try renaming it and then rebuilding.
please can you give me some images to under stand what can I do … thanks
Your output log says the AutomationTool failed to compile, because it ran into an unexpected error creating a debug information file located at ‘c:\Program Files\Ue4\Engine\Source\Programs\AutomationToolLauncher\obj\Development\AutomationToolLauncher.pdb’
I’ve highlighted the line in your log, below.
Navigate to the AutomationToolLauncher.pdb file in the given path above. The engine is attempting to write to or overwrite this file during the build process, and is likely encountering this error because it does not have permission to do so. Check the file’s properties and ensure it is not set as Read-Only, and that your user account has Full Control over the file.
You may have another process running that is utilizing the file and has locked it for editing. Ensure you’ve closed down any programs that are unnecessary.
If none of that works, try renaming the AutomationToolLauncher.pdb file to something else. (Don’t delete it, just rename it). This way Unreal Engine won’t have to deal with the old file during the build process, and instead should simply create a new PDB file with the appropriate permissions.
thanks
