Still get application error at least once per day running tightvnc 22.214.171.124 on XP operating system. Windows 7 runs clean.
software exception 0xc0000417
I have same errors.
Tightvnc server 2.7.10 installed on Windows XP SP3 (+updates) as a service. Windows is running in virtual machine (KVM).
DFMirage driver is installed.
Client (vinagre) is standart remote desktop viewer on debian/ubuntu.
tvnserver.exe crashed periodically, several times a day.
I found that the problem is probably due to old driver DFMirage. For 32bit XP available only old driver version 1.1.68 (2005). This old version installed from latest dfmirage-setup-2.0.301.exe package.
If i disable old DFMirage driver then the problem disappears.
The problem can be reproduced as follows. Sequence is important.
1) Reboot windows.
2) Do logon proccess (enter login/password)
3) Sorry, next is my bad translation from my russian windows xp user interface.
My computer -> manage -> event log -> applications
You will see the event log entries.
Find any event marked "error" (red color) and open it.
In the bottom you see hexadecimal data in a little window
with a scrolling controls. Click the mouse a few times on the down scroll arrow, then click few times on the up arrow. Repeat this 2-3 times. At this moment tvnserver.exe typically freezes.
