Download and execute the package file {win32} (Windows 7 or later,
32-bit) or {win64} (Windows 7 or later, 64-bit) following these
instructions:
* Install _WSJT-X_ into its own directory, for example `C:\WSJTX` or `C:\WSJT\WSJTX`, rather than the conventional location `C:\Program
Files ...\WSJTX`.
* All program files relating to _WSJT-X_ are stored in the chosen
installation directory and its subdirectories.
* Logs and other writeable files are normally found in the
directory +
`C:\Users\<username>\AppData\Local\WSJT-X`.
TIP: Your computer may be configured so that this directory is
"`invisible`". It's there, however, and accessible. An
alternative (shortcut) directory name is
`"%LocalAppData%\WSJT-X\"`.
* The built-in Windows facility for time synchronization is usually
not adequate. We recommend the program _Meinberg NTP Client_: see
{ntpsetup} for downloading and installation instructions. Recent
versions of Windows are now shipped with a more capable Internet
time synchronization service that is suitable if configured
appropriately. We do not recommend SNTP time setting tools or others
that make periodic correction steps; _WSJT-X_ requires that the PC
clock be monotonically increasing and smoothly continuous.
NOTE: Having a PC clock that appears to be synchronized to UTC is not
sufficient. "`Monotonically increasing`" means that the clock
must not be stepped backwards. "`Smoothly continuous`" means
that time must increase at a nearly constant rate, without
steps. Any necessary clock corrections must be applied by
adjusting the rate of increase, thereby correcting
synchronization errors gradually.
[[OPENSSL]]
* _WSJT-X_ uses the _OpenSSL_ libraries, and these are usually
installed by defajult. If an incompatible OpenSSL version is already
installed on your system. you will see the following error message
shortly after requesting a fetch of the latest LoTW users database. To
fix this problem, install the _OpenSSL_ libraries.

You can download a suitable _OpenSSL_ package for Windows from
{win_openssl_packages}; you need the latest *Windows Light*
version. For the 32-bit _WSJT-X_ build, use the latest Win32 v1.1.1
version of the _OpenSSL_ libraries, for the 64-bit _WSJT-X_ use the
latest Win64 v1.1.1 version of the _OpenSSL_ libraries (Note: it is OK
to install both versions on a 64-bit system) which, at the time of
writing, were {win32_openssl} and {win64_openssl} respectively.
Install the package and accept the default options, including the
option to copy the _OpenSSL_ DLLs to the Windows system
directory. There is no obligation to donate to the _OpenSSL_
project. Un-check all the donation options if desired. +
NOTE: If you still get the same network error after installing the
_OpenSSL_ libraries then you also need to install the
{msvcpp_redist} component. From the download page select
`vcredist_x86.exe` for use with the 32-bit _WSJT-X_ build or
`vcredist_x64.exe` with the 64-bit build, then run it to
install.
TIP: If you cannot install the _OpenSSL_ libraries or do not have an
Internet connection on the computer used to run
_WSJT-X_ {VERSION_MAJOR}.{VERSION_MINOR}, you can download
the _LoTW_ file manually. Go to
https://lotw.arrl.org/lotw-user-activity.csv in a web browser,
download the file, then move it to the _WSJT-X_ log files
directory. This directory can be opened by selecting
*File|Open log directory* from the main menu.
* _WSJT-X_ expects your sound card to do its raw sampling at 48000 Hz.
To ensure that this will be so when running under recent versions of
Windows, open the system's *Sound* control panel and select in turn
the *Recording* and *Playback* tabs. Click *Properties*, then
*Advanced*, and select *16 bit, 48000 Hz (DVD Quality)*. Switch off
all audio enhancement features for these devices.
* You can uninstall _WSJT-X_ by clicking its *Uninstall* link in the
Windows *Start* menu, or by using *Uninstall a Program* on the
*Windows Control Panel | Programs and Features* option or in
*File | Settings | Apps*.
