The trial version should be full functioning.
>Import from Spreadsheet wizard doesnt allow to finish ,it comes up to the step copy from excel sheet . But the "Finish" button is not activated in it.
The FINISH button is grayed out until there is data copied onto the clipboard. So, at that final point in the New Form Assistant (wizard) you would open the spreadsheet (in Excel), copy the selected cells you want, return to LiveCycle Designer program to "FINISH".
