Re: vncviewer 1.2.3.1 open a dialogbox
I reinstalled, but was still having troubles. Same dialog window appeared when opening Viewer - asking about options.vnc file. Luckily, the problem was solved after restarting computer.
Re: vncviewer 1.2.3.1 open a dialogbox
Likely your Viewer was running while the new package was installed. So your Viewer exe was locked. The installer does schedule a "rename" task for next reboot then to replace the file on reboot. It's essentially the same reason why Windows needs to restart each month after Windows Updates; to replace locked files.diggdagg wrote:I reinstalled, but was still having troubles.

Make sure you close down all UltraVNC processes (Server, Viewer...) before running an installation in order to avoid having to reboot.
