Hello,
I installed openvpn-install-2.3.4-I603-x86_64.exe under Vista 64 SP2 and it didn’t work. VPN connects but don’t work and openvpn-gui can’t stop openvpn process. I have tried manually signaling the event sent to openvpn via command line but it seems that openvpn wasn’t waiting on that. In this scenario a boot was impossible because openvpn didn’t die. I have to poweroff the computer each new try (annoying and dangerous) ! I uninstall i603 and install openvpn-install-2.3.4-I003-x86_64.exe and everything works as expected including the manual signaling of event (I did it just to be sure, not a normal operation). The connection is usable, but slow. Probably a network related problem. I’m not sure if this is a bug or not. Regards Jorge Ramos
