Snapshot. I can't restore snapshot on other server

I download ZIP file and snapshot-installer.php file from HUB, I upload those files to correct folders, but during the process of restoring a get an error:

We could not locate the wp-config.php file in your backup.
We could not locate the Snapshot manifest file in your backup.

There was a problem with the htaccess file – a line that was duplicated and needed to be deleted. And an issue with the robots.txt so I was told to delete that file from the backup and try again. I did those steps, but now stuck cause it says it can’t locate the wp-config, but I checked and it is in the backup zip file.
