About installer you are right, about binaries I would download
https://ci.appveyor.com/project/FreeTDS/freetds/build/643/job/ct9rf92mw0vcyv3l/artifacts
or
https://ci.appveyor.com/project/FreeTDS/freetds/build/643/job/h5h5h2oekntgaqg3/artifacts
(32 or 64 bit) and register tdsodbc.dll with regsvr32 utility.
You should download and install OpenSSL from
https://slproweb.com/products/Win32OpenSSL.html before.

In win32 directory there is an old source for a NSIS installer but
probably would require some additional library (MSVC/OpenSSL).
