Some versions of Crystal Reports export to DOC format, but actually they produce reports in RTF format (Rich Text Format) and giving them the .DOC extension by default.
Could you please attach here or to helpdesk a sample document, so we could check this.
The RTF document format doesn't support signing and it is not supported by OfficeBlackbox components.
