Axxon PSIM software can be launched automatically from the Startup function, as soon as Windows OS services and shell start downloading.

To configure the Axxon PSIM system launch from the Startup function, the Axxon PSIM system icon should be placed in the Startup group of the Start menu.

In Windows 8.1 and Windows 10 for the proper operation of the Startup function, create a registry key with an arbitrary name in the HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Run (if the OS is 64-bit) or
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run (if OS is 32-bit).
The path to the executable file is to be specified as the key value, for instance: C:\Program Files\Axxon PSIM\psim.exe

Also, disable UAC completely as described in OS settings for correct operation of Remote Admin Workstation or Server.
