When ends users try to modify or create a new report, the error "Attempted an unsupported operation." appears:
The problem is caused because DSM Reporter is installed on a remote Agent which has a language different than English configured (for example, Spanish).
Every management component (like DSM Explorer / Reporter) is not supported having Spanish language configured, the only supported languages are: English, French, German and Japanese. Here is the detail of the supported languages:
