This error I see from time to time and I must say: It is so frustrating that it is not more descriptive. Don't know if an MSI issue or AdvancedInstaller.
For this user this is their log: I would love some direction as to what the fatal error cause is here please. I marked in red the Fatal Error area. Maybe I just need to be taught how to properly read these. Apologies if a newbie question. I searched the forums and found other 1001 errors but nothing that helped with this.
