1. Start Crystal Reports.
2. When attempting to open an existing report, it displays the error:
        
        "This document could not be opened"

• There are at least two parameters with identical names in the report and one is unused.
• Crystal Reports version 9 had a product defect allowing identical names for parameters, this issue was resolved and it is now no longer possible to have 2 parameters with the same name. And if it occurs, it is unfotunately not possible to open the report in Crystal Reports.

• To resolve the issue, open the report in Crystal Reports for Enterprise designer, and delete or rename the unused parameter with duplicated names.
