Hello!
The customer on a Siemens Industrial PC has UltraVNC 1.0.5 release. (Original Siemens, I wasn't allowed to upgrade anything)
FileTransfer doesn't work: "FileTransfer is Disabled on the Remote Machine"
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 FileTransfer?
The current ultravnc.ini:

FileTransferEnabled = 1
is still the same in the latest 1.5.0.4
It also require
InputsEnabled=1
A user must be logged on in
The UltraVNC Viewer needs to be UltraVNC and best is to use the same version as the UltraVNC Server to be sure they speak the same protocol.
The UltraVNC Server needs to answer the UltraVNC Viewer he is UltraVNC to enable this option on the UltraVNC Viewer.

Re: FileTransfer funktioniert nicht
Hello Rudi De Vos,
thank you very much for your help!
I have already:
FileTransferEnabled = 1 (This line was completely missing)
InputsEnabled=1
But unfortunately with the same result. ("FileTransfer is Disabled on the Remote Machine")
What else could it be?

Re: FileTransfer funktioniert nicht
Then I need the server log to see something more.
Normal when UltraVNC Viewer/Server are the same UltraVNC version this should work.
This is the default behaviour after install.
The settings in 1.5.x.x show the location of the config file
Pre 1.5.0 this is next to the winvnc.exe
Rename ultravnc.ini and restart winvnc.exe, this create a new default ultravnc.ini
Set the password again and try to connect
FileTransfer checks if the version support it and that FileTransfer is not disabled
