Security Plugin

[Cardone]

I am trying to move from a Windows XP SP3 (32-bit) system with UltraVNC 1.0.8.2 to a new computer with Windows 7 Professional (64-bit) with UltraVNC 1.0.9.6.1.

On the old XP system, UltraVNC works beautifully with or without my security plugin. On the new Win7 system UltraVNC works fine without the security plugin, but if I try to use the plugin I receive the following message.

The plugin cannot be loaded. Please check its name integrity.

I have done nothing to the plugin to change it. Its name is "MSRC4Plugin_NoReg.dsm"

Many of the computers I connect to use this plugin and it would be difficult to make any changes to it.

Thank you for any and all help in advance.

Looks like you are using a 32bit plugin with a 64bit exe

I did not realize the plugin was tied to whether it had been generated as a 32-bit or 64-bit key.

So does this mean the 64-bit UltraVNC is incapable of accessing the 32-bit version of UltraVNC if the security plugin is used?

Cardone, I could be wrong but I don't think Rudi was talking about the key length -- he was talking about the plugin executable's compilation.

Seems you understood me wrong

A plugin (dsm) is a dll.
You can't mix 32bit exe with X64 dll's or X64 exe with 32bit dll's.

It has nothing to do with the encryption key, but mixing of 32/64 exe/dll's.

When i'm correct, the old plugin MSRC4Plugin_NoReg.dsm only existed as (32bit dll)
Error: winvnc (X64) can't work with a win32 dsm plugin.

You can use
server X64 + dsm X64 <----> viewer win32 + dsm win32 OK
server w32 + dsm w32 <---> viwer x64 + dsm x64 OK
server X64 + dsm w32 FAIL
viewer w32 + dsm X64 FAIL

I understand.

Thank you for the clarification.
