UltraVNC 1.2.0.1 Viewer Crash

[sbostedor]

Curious if anyone else has ran into this.

I've installed UltraVNC 1.2.0.1 on a Windows 8 (x64) PC with default settings and a vnc password. I copied the vncviewer.exe file to my personal Windows 8 (x64) PC. When I run the vncviewer.exe at my PC and connect to the remote PC, the viewer constantly cycles through reconencting and never stays connected.

I've chosen multiple other similar PC's on the network and have the exact same result.

If I put that same vncviewer.exe on a Windows 2008 r2 computer and connect to the very same Windows 8 (x64) computer running the server, I have no problems at all! It's only happening if the computer running the vncviewer.exe is running Windows 8 or Server 2012.

Any ideas?

I should add that the server is being installed in service mode and UAC is enabled on all computers.

The viewer doesn't have any OS depended parts... but anyway i tested the viewer again on a win8 and win8.1, both work without problems.
The viewer talk rfb with the server, this is independed, it doesn't matter if you connect to a linux/ windows or mac server that talk rfb. The windows OS of the server has no influence on the viewer.

The only way i know you can loop is when you have the server option ( lock on disconnect) set.
Viewer connect, you enter unlock code, server switch session, viewer disconnect
server lock again because viewer disconnect, you logon agaiin, unlock etc...

The problem need to be narrow down.
1° Run server as application and try with a win8 viewer. If a viewer crash, he should always crash and it would not depend
on the server otpions.
