This issue could appear in 2 cases:
1) Either you did not install theme properly and file xstoreN/framework/thirdparty/envato_setup/envato_setup.php is missing
2) or you see this issue because of file permission.
If you check the xstoreN/framework/thirdparty/envato_setup/ folder and file exists then contact your hosting provider to fix file permission issue.
Reply back if it does not help and provide FTP and admin panel access in Private Content area.
