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.
