Verifying Your Designer/Viewer Status
If you are only licensed as a Viewer in Jet Essentials, the Jet/Design option will be grayed out and will not be usable. If you are licensed as a Designer, then the Design option will be available. If you should be licensed as a Designer and you do not get the Design option, there are two common problems.
If Jet Essentials cannot find a valid Jet license file, you will not get the Design option. You should check that your Jet license file (.JLF) is in the Jet License File Path specified in the Application Settings (default: C:\Program Files\JetReports). You can test the integrity of your data source configuration by clicking the Test Connection button on the Data Source Settings. You should receive a message that you are licensed as a Viewer or a Designer. If there is a connection problem or a problem with your Jet license, you will get an error message related to the cause of the problem.
If your user name in Excel does not match your name in the Jet Reports license file exactly, you will not get the Design option. To verify that your name is entered in Excel correctly, click the text reading "You are licensed as a..." on the Data Source Settings window. If you scroll down, you should see a list of designer names. Your name here needs to match your Excel user name, which you can find in Excel's Options...
