Dear Users,
Some people were asking me for a standalone stunnel.exe file. It's located in stunnel-4.12/src directory of stunnel-4.12.tar.gz archive. Winzip can handle .tar.gz format, so you'll be able to unpack it. http://www.winzip.com/wzdifs.htm
BTW: I recommend to try the installer, anyway. It's designed to make the upgrade much easier. You can simply enter the path where your current stunnel.exe and stunnel.conf are located during the install. stunnel.conf and stunnel.pem files won't be replaced and your Windows will remember the path so you won't have to enter it on next upgrade. Also the latest OpenSSL DLLs are installed in stunnel directory each time.
Notes: 1. Uninstall removes stunnel.conf, so don't uninstall if you're only going to upgrade stunnel. 2. Remember to stop stunnel before you uninstall/upgrade it.
Best regards, Mike
