[stunnel-users] clean installation on Windows

[John]

Hello. I would like to install stunnel on 64-bit Win7, and I would like to 
know whether it is possible to do so by just unzipping the downloaded files 
into one folder and then clicking on the main executable, that is, to avoid 
making registry entries, etc. I would like to have a minimal impact to 
whatever extent is possible. Can it be done in this way, or does it need the 
whole shebang installer procedure to be run?
