Error in WinVNC SCIII on certain machines

Post by nir_kornfeld »

Hello,

I'm getting the following errors on certain Win98 machines when using VNC SC (Both version 3 and not).

The error dialogs appear after selecting any ID from the list. The second error dialog appears on top of the first one.

The same EXE works on other machines without any problem.

Any ideas? Must be something with a certain support DLL or Run-Time as far as I understand this... But....

Thanks.

winvnc.exe (normal version)runnning + SC don't work.

My opinion the WinNC usage message comes from winvnc.exe.
If SC detect winvnc, he send his command line to the running version.

But how can I tell which version is it?
The SC self extract archive contains a file named "WinVnc.exe"

Don't you think it has anything to do with the first error message?

I've checked the client computer and did not find any vnc instance in memory, but still the same message...

Any other ideas? Maybe some kind of a debug trace to see where it gets the error?

How do your create your SCIII?? did You make sure that you added the certificate.pem file to your *.zip file. This version uses SSL so you do not need a rc4.key. You have to make sure that your port 443 is forward to your repeater.

Didn't noticed it was SCIII

1) .pem is only used on the repeater. Server act as ssl client (like web browser), no need to add pem.
2) port 443 need to be open
3)[DEBUG] in helpdesk.txt generate some debug info

It could be that the proxy detection on 98 is little different.
I know in the previous version, a crash happened when iexplorer had never set a proxy before (reg key missing) --> var==NULL -->crash
But this should be fixed in the latest version.

But anyway, possible something to verify to track the bug.

As I mentioned in the first post, the same self-extract-exe works on many machines without any problem (and over ssl:443 connection).

It has problems only on certain win98 machines - so I can assure everybody that this SC package is fine.

The problem I have must origin from somekind of a bug in the winvnc.exe which is included in SC.

winvnc info:
version: 1.1.0.0
Dated: 13/11/2005
Size: 315392 bytes


Rudi,
How can I get more details or debug info about the cause of this error?
Should I add the [DEBUG] keyword to helpdesk.txt ?
Should I try to add a dummy proxy server to iexplorer and remove it. so the registry key will be created?

Thanks.
