WinTox

Here I found two still working links:
wintox_win32.zip and wintox_win64.zip.
No any source code, only compiled binaries, and this is standalone and portable exe-cutables.
You can find this in this zip-archive in ./wintox/wintox_original/-folder.

wintox.exe (x86, win32), this is oldest known version of uTox, which can working on Windows XP.
This was been released in 2014 year, and not supporting calls, and video calls,
but this program have a small size, supporting assymetric NaCl encryption-decryption,
and this is a p2p program, it can find a peers and connect them,
even in LAN, without connect to Internet!

Now, with my additional scripts, anyone can generate his modified wintox.exe
with custom nodes and ports.
Only two nodes available there, because too small size to rewrite in exe-hexdump.

In future releases, I'll try to rewrite this scripts for uTox v0.7.0, which is too working on Windows XP.

Best regards, and enjoy.

Stable XP version - uTox v0.7.0

This is a stable portable version, which is working on windows XP.
I cann't compile this from the source code,
and cann't find corresponding versions of libraries,
so I just attach there the binary x86 executable file uTox_winXP.exe
and start_portable.cmd - to start this as portable application.
Else tox profile writted and saved somewhere in:
disk:\Documents and Settings\User\Application Data\Tox\

unknown_uTox_XP

This is another unknown verion of uTox.exe, which is compatible with Windows XP.
I did found this on my HDD, and cann't understand what version this is.
No any source code, but this is standalone executable, and this is portable.
This "uTox_winXP.exe" supporting calls, and video-calls. File-profile name is "utox_save",
and maybe DHT there is more optimized, than "wintox.exe".

See "What is this.txt" with detail description.
