Re: pgAdmin4 v9.2 causes unexpected Windows Server reboot during silent installation

Hi, Aditya Toshniwal

Thank you for your reply.

We understand that the pgAdmin installer itself does not explicitly request a system restart.
However, we experienced automatic reboots on several Windows Server 2022 systems immediately after installing pgAdmin 4 v9.2 (pgadmin4-9.2-x64.exe) in silent mode.

Event Viewer shows Event ID 1074 (process: winlogon.exe, user: NT AUTHORITY\SYSTEM).

We are wondering if, during the installation,
the installer might trigger the installation or update of dependent modules (such as Visual C++ Redistributables or Python runtime),
which in turn cause Windows to request a system restart.

Could you please confirm whether this behavior is expected
or if there are any known dependencies that may require a restart on first installation?

Thank you,

Shumpei

Hi Shunpei,

pgAdmin installer does not require system restart.

Dear pgAdmin Support Team,

We are using Windows Server 2022 and encountered unexpected system reboots right after installing pgAdmin4 v9.2 (pgadmin4-9.2-x64.exe) in silent mode.

Event Viewer shows Event ID 1074 (winlogon.exe, user: NT AUTHORITY\SYSTEM). 
Could you please confirm if the installer intentionally triggers system reboot or if there is a known issue related to this version?

Thank you for your support.

Best regards,
Shunpei Sakanoue
