Backup.exe Error

[ixirhost]

Hi Dear;

Plesk 8.6 for windows I'm using panels. "Plesk Backup" tool to connect with remote desktop, I want to take the backup. But what if I choose 1 domain or all domains "saving" is not just text and can not substitute in any way.

When I look in event viewer backup.exe has created an error as follows.

1) Unable to back up package 'CommunityServer'.
