Trooper WinVN Usenet News Reader Winvn icon

Last update Jan-21-2018
My favorite Usenet News reader WinVN has been dormant in the development department for more than a decade, so I've updated it myself. I initially updated the original NASA maintained source from here , but later found a much improved German version maintained by Peter Heirich. I've incorporated my changes into these versions. I used Jordan Russell's nice, free, installation program INNO Setup to handle WinVN's install/uninstall.

Choose the file to download:
Platform Files
winvn17-all.exe v0.99.17.0 (1.2MB)
Installer for all platforms Win95-Win10, 32 & 64bit!

*SSL support requires OpenSSL V1.0.2 available at

32 bit x86
(For All windows versions Windows 95 through Windows 10)

*SSL support requires OpenSSL Win32 v1.0.2 x86 available at

Because SSL can use strong crytography it can be illegal to export the files to certain countries. So rather than have to deal with export restrictions, you'll have to find the files yourself.
64 bit
x64 version x64
(For 64bit Windows XP through Windows 10)

*SSL support requires OpenSSL Win64 v1.0.2 available at

for developers Winvn source code V17 (4.0MB)
Be sure to remove any old gwinsock.dll files from the WinVN folder! (It's now built-in)
Recent changes:
Additional fixes by Ray Dunn
Additional fixes from Peter Heirich's 0.99.10 beta4 [de] version
See many addtional changes in readme.txt file in the archive.
(TIP - Use WinVn with UUDWin's monitor file option to easily process files while they are being downloaded!) X
