Culture Name: en-EN is not a supported culture

I got this error on my installation.
What does it mean ?
How can I solve ?
Tks.

This exception means that custom culture settings of your environment are not supported. As workaround we recommend to use alternative name of an existing culture for Aspose.PDF internal functionality:

com.aspose.pdf.LocaleOptions.setLocale(new Locale(“en”, “US”));

Already done but the problem is still there.
The error is the same with en-EN error (not US).
I did the operation, once for all, after I set the license.
Is there any other place where should I put the instruction You suggested ?

Tks for the operning of the ticket.
Could You explain me better what should be installed in the target machine in order to solve the issue.
In my test machine everything works fine.

All that needs to be done is to apply a locale supported by the Aspose.PDF project before the license is activated.
The following line without changes must be called before other classes of Aspose.PDF even before the license:

com.aspose.pdf.LocaleOptions.setLocale(new Locale(“en”, “US”));
