Issue with file transfer (Explorer)

[Bars7878]

Hi! We got issue with enabling file transfer. Server runned as a service. Windows 10 machine work as kiosk without explorer,
the interface is replaced by application software. . After reboot we can enable file transfer, but after closing window of file transfer we can not start file transfer again with error "Warning: File transfer is disabled on the remote machine" but file transfer is enabled in server parameters.

When we start explorer manually file transfer work again as expected.

Please, help us with understanding and resolving this issue.

The server use the explorer.exe to set the security level.
You can try 2 things

1. For FT set impersonate user off ( server option), then the FT is done as system
2. Use an alternate shell, usual a kiosk pc has his own shell
   Add following to the ultravnc.ini
   [admin]
   alternate_shell=My.Alternate.Shell.exe
