As you will see many time in the forum and also in the user manual troubleshooting, the error "Unable to write entry" mean that you don't have permission to write on some file.
The file name that is reported is not necessarly the reason.
This maybe also another files that would cause this problem or another security permission.
If you have plenty of files listed in the list of patches that reports that you don't have write permission, try to solve them ALL before retry.
You can also try using the FTP Layer as explained in the video 15.

See FAQ that present this case.
You also have to check that the directory have correct permission.
