update from VCLProduct-12.1.6 to VCLProduct -12.2.2 or 12.2.3 - application crash

I would recommend reporting the actual error (Exception class and error message) along with the callstack. You can use the free version of madExcept to help do this.

Hello,
Mr. Woolls is completely correct. You can use the information provided in the How to get the callstack in the IDE? Knowledge Base article to learn how to collect CallStack information. However, it would be much better if you provide us with a sample project so that we can precisely replicate your scenario on our side.

Mr. Nathanial :-)

I stand corrected. Should read, Mr. Woolls. I have corrected my previous reply.

Hi it is not possible to do it with madExcept or CallStack. Delphi XE2 hang completly and i can do nothing. In the debug modus
it crash at:
Form1:= TForm1.Create(Application);
source code :
  if Umgebung = 0 then begin
    Umgebungname := 'Produktiv-System (Netz)' ;
    //if (MessageDlg('System auf Produktiv - Umgebung mit Netz umstellen?', mtConfirmation, [mbYes, mbNo], 0) in [mrYes]) then begin
      Screen.Cursor := crSQLWait;
      DataModule1:= TDataModule1.Create(Application);
      datamodule1.datamodul1ende ;
      //datamodule1.MSLogin.Active := false ;
      datamodule1.MSConnection1.Connected := false ;
      datamodule1.MSConnection1.Disconnect ;
      datamodule1.datamodul1start ;
      Form:= TForm1.Create(Application);
      form1.dxStatusBar1.Panels[5].Text := Umgebungname+' '+Standortname ;
      Screen.Cursor := crdefault;
      SplashForm.hide ;
      form1.ShowModal ;
    //end ;
