1) upload custom.zip
2) This give you a sc.exe that include the plugin
3) use 7zip the extract the sc.exe or run sc.exe and copy the latest folder in the %TEMP% folder, this has the extracted sc.exe (copy the files before closing sc.exe else they get deleted)
4) Copy this plugin in the viewer folder ( SC=32bit -> Viewer need to be 32bit)
5) Create the key via the viewer call it rc4.key and copy it in the server folder
6) test it with the local sc folder

SC is older then 10961, and can't work with the new plugins.

first at all - ty for answer :)

im not pretty sure that i understand this correctly,

- i need to upload prepared custom.zip by me ? with my helpdesk.txt ? what files need to be in this custom zip ? [ you dont mean that i need upload custom.zip that i download for site without any changes ? yes ? ]
- "copy the plugin in the viewer folder" - after installed ultravnc i have 1 folder with all files, dont have folder for viewer exacly...
- when i start "Run UltraVNC Viewer (Listen Mode Encrypt) i can create 2 key (for server and viewer (*.pkey and *.pubkey) - i need to rename one of them to rc4.key ? server key or viewer key ?
- "test it with the local sc folder" - what do you mean with that ?

sorry for all this question ;/ im not "idiot" even if it looks like this but i wonna make everything correctly ;/ im a graphic designer, not programmer or something :(

waiting for more specific info :( :)

1) unload unmodified custom.zip to get a sc.exe
The First goal is to get security plugin used by sc and create a local folder with all files
that can be used to test how it gonna look...

sc.exe is a self extracing archieve ( 7zip)
The best way is to install 7zip ( http://www.7-zip.org/), this allow you to unzip sc.exe

You will see that you get a folder with
winvnc.exe*
schook.dll*
vnchook.dll*
MSRC4Plugin.dsm*
background.bmp
helpdesk.txt
icon1.ico
.....

Copy a win32 version of vncviewer.exe in this folder, and select to use MSRC4Plugin.dsm as plugin
config, this generate rc4.key

You can also test the changes you make by executing winvn.exe

Remove the files with* and vncviewer.exe before creating the zip for the fibnal upload.

ok, i do like you say :
==========================================
windows 7 ultimate 64 bit
ultra vnc 32 bit - full instalation
==========================================

1. download custom.zip

2. use UltraVncSC based on RC23 (2005) to make custom.exe file

7. copy vncviewer.exe from ultravnc installed folder to "help" folder (name of my sc.exe that i wonna prepair)

8. copy all files from custom.exe (open by 7-zip) to "help" folder (with MSRC4Plugin.dms)

9. use vncviewer from "help" folder to generate rc4.key (it make new_rc4.key - delete rc4.key and rename our key to rc4.key)

10. copy rc4.key to ultravnc folder

11. copy MSRC4Plugin.dsm from "custom.exe" to ultravnc folder

12. delete from "help" folder :

winvnc.exe*
schook.dll* [ i dont have in "custom.exe" file with this name ]
vnchook.dll*
MSRC4Plugin.dsm*
and vncviewer.exe

13. configure helpdesk.txt and icon, logo etc.

14. make zip from "help" (will be "help.zip")

15. use UltraVncSC based on RC23 (2005) to make help.exe file

16. run UltraVNC Viewer (Listen Mode Encrypt)) (from start menu)

17. on second computer start help.exe file


===

on computer where i start "help.exe" (computer 2) i get information that i got connection, icon its in try but
on computer 1 i see "The Plugin cannot be loaded. Please check its name integrity."

====
when i close connection on computer 1 (press ok on this error window) i get message like this one :

"Connection failed - Invalid protocol !

Possible causes :
- You've forgotten to select a DSMPlugin and the Server uses a DSMPlugin
- Viewer and Server are not compatible (they use different RFB protocols)

===
when i click on icion in try (ultravnc viewer) on computer 1 and press "new connection" i see that dont have mark on
"use DSMPlugin"

whats the problem now ? :) where i make a misteake ?

The Plugin cannot be loaded. Please check its name integrity
The error tell that you are mixing 32bit dll's with 64bit exe or invers.

I guess you are using a 64bit viewer with the 32bit dll (plugin), use a 32bit viewer.

Just put the error "The Plugin cannot be loaded. Please check its name integrity" as search on top of the forum.
It's a 32/64bit issue...
