Add-on Status is Failed, but Add-on is connected

Question

Good Day!
Hi Experts,
I had created an installer for my Add-on for the client. This is a project from SAP B1 Studio.
SAP B1 version is 9.0 PL11.
1. The add-on is running ok in Debug Mode.
2. I've successfully created an ARD File.
3. Successfully installed ARD File.
4. On Add-on Manager, when I tried to click Start, the add-on says Incorrect Connection String for Add-on. Even if the Status is Failed, the Add-on still executes. It still displays the custom form, the events, CFL etc.
I've used the SAPBouicom.Dll in my debug folder, and I ensured the latest SAP B1 Studio and DI API is installed (PL11). I even removed the old files and reinstalled but the same result appears.
Your help is greatly appreciated in this matter.

i had already a Debug Code in my Environment.
Dim sConnectionString As String
SboGuiApi = New SAPbouiCOM.SboGuiApi
sConnectionString = Environment.GetCommandLineArgs.GetValue(1).ToString
                Try
                    SboGuiApi.Connect(sConnectionString)
                    ' Causes an Error Here but if I don't terminate the Add-on here, the Add-on will still run
                Catch ex As Exception
                         'System.Windows.Forms.MessageBox.Show("No SAP Business One Application was found")
                         'End  
                    Try
SBO_Application = SboGuiApi.GetApplication()
