In specific application I am using Crystal Reports. In 32 bit environments I have not any problem, but in 64 bit (Windows7) in Forms Viewer I give this notice: Failed to load database information. Details: The database DLL ?crdb_dao.dll could not be loaded. Error in file c:\Users\edik\AppData\Local\Temp\1_kruz.rpt {311E8091-4F44-47E6-A101-D6F8041014C8. Failed to load database information.
