Filetransfer funktioniert nicht

[Stan777]

Hello!
The customer on a Siemens Industrial PC has UltraVNC 1.0.5 release. (Original Siemens, I wasn't allowed to upgrade anything)
File transfer doesn't work: "File Transfer is Disabled on the Remote Mashine"

In an earlier version I had to do this in ultravnc.ini: FileTransferEnabled=0 -> 1.
Now the ultravnc.ini get file didn't have a line: FileTransferEnabled.
I typed it in, but that didn't help at all.
How can I turn on file transfer?

The current ultravnc.ini:

The viewer need to be UltraVNC and best is to use the same version as the server to be sure they speak the same protocol.
The server need to answer the viewer he is UltraVNC to enable this option on the viewer
