I'm having the same problem. I get an error message prior to this that says there is a problem with the plugin name integrity.

I've made sure that the plugin is the same in the exe file as on server side. that I'm in listen mode and pointed at the right plugin file (tried both absolute and relative path). Still no go.

I know the files aren't corrupt because it'll work fine if I do a regular connection. It's only when I try UltraVNC SC (reverse connection) that this happens.

I've been working on this issue for a little over a month and honestly have gotten sick of it. Free software is great, but I need functionality and I'm about ready to pay for it.

Please let me know if you find the solution.

Plugin UltraVNC Viewer
- You should have the special "for SC" plugin, MSRC4Plugin_for_sc.dsm in the UltraVNC Viewer folder (The plugin is part of the x86 addons)

Plugin UltraVNC Server
- Auto added by creator

The creator is a SFX file, you also can use 7-Zip to extract it, inside you have the plugin, you can also use this plugin for the UltraVNC Viewer but the MSRC4Plugin_for_sc.dsm is the correct one.

UltraVNC SC requires a 32-bit plugin + UltraVNC Viewer 32-bit.

HOWTO:

* Install 7-Zip to be able to extract the downloaded .EXE from the UltraVNC Online SC Creator.

This is easier for testing, so you don't have to use the creator each time.
Extract the SFX to a folder where you have UltraVNC Server (winvnc.exe...).

* Run UltraVNC Viewer and select the MSRC4Plugin_for_sc.dsm plugin
- Select [v] use DSMpluigin press config to create the rc4.key (new_rc4.key)
- Copy this key to the UltraVNC Server (winvnc.exe) folder and rename it to rc4.key
- [v] save connection settings as default (then you don't need to add a commandline for the encryption)
- Close the UltraVNC Viewer

+ Start UltraVNC Viewer: vncviewer.exe -listen
(Tray icon show Viewer listening on port 5500)

* UltraVNC Server (winvnc.exe) folder
+ Edit helpdesk.txt
- plugin -connect 127.0.0.1:5500 -noregistry
(127.0.0.1 = localhost, this allow to test the connection with UltraVNC Server/Viewer running on the same pc)

Run UltraVNC Server (winvnc.exe) for testing.

When all is ok, create a .ZIP with custom icons, helpdesk.txt and the rc4.key.
