We have an installer with Advanced Installer version 19.6. We are facing an issue where after the reboot of the PC, the installation starts again.
We are using the "Force Reboot After Install" feature of AI. When the installation is complete, we restart the PC using the Reboot prompt. Sometimes it happens that after the PC is restarted, the installer starts installing again. After the prerequisites installation, it shows us the "Modify, Repair, and Delete" window.
If I close the installation prompt, the application works fine. We are struggling to find the reason behind the problem. It doesn't happen all the time. It mostly happens in VMs where the resource is limited but we could not establish any reliable pattern.
FYI, we are running some PS and batch scripts as custom actions and in all those scripts we use the "Wait for custom action to finish before proceeding" option. So, the scripts should not cause any issues because they should execute one after another.
We also do not use the "Reboot system after installing this prerequisite" option for any prerequisite.
Is this a bug of Advanced Installer? If not is there any suggestion on how can we pinpoint or debug the problem?
