The best way to get set up with Pathway is to use the Bootstrap program by clicking this download link:

Download
It will install Pathway and any necessary supporting software to make the most effective use of the program. If you would like to check the validity of your download, you can use the fciv tool from Microsoft. This version of the program should give you:
>fciv PathwayBootstrap-1.20.exe
//
// File Checksum Integrity Verifier version 2.05.
//

If you prefer to have greater control of the setup process, you can download any of the individual installers below.
In order to determine the version of FieldWorks, launch the FieldWorks program (Language Explorer or Translation Editor) and go to the Help menu and then the About item. The version of FieldWorks is given in the main part of the form, under the words SIL FieldWorks. Similarly, for Paratext, launch Paratext. The version is given after the word Paratext in the main part of the form.
The Language Explorer (Flex) will work with either BTE or SE but both Paratext and TE require BTE.

Installing Pathway
Make sure to remove any previous versions of Pathway by selecting Start on the Task bar and choosing Control Panel. Select the Add / Remove Programs icon. Find Pathway in the list. Right click on it and select uninstall or with Pathway selected, choose uninstall from the File Menu.
After downloading the installer (or installers) above, double click to begin the install. You will be asked a series of questions. After responding to the questions, the installation will begin automatically.
Some users has had difficulty with style sheets and settings left by a previous version of the program. This is somewhat unusual and should be reported to the development team so it can be addressed in a future version. Your settings are saved and should work even when a new version is installed.
Installing Pathway on Linux
The download links for the experimental packages on Linux are below. After downloading the appropriate package for your Ubuntu Linux installation, launching it will allow you install it. Once this installation process if finished, it is necessary to open a terminal window (CTRL-ALT-T) and type the ConfigurationTool command. This will set up the registry key needed by FieldWorks (or Paratext) to use Pathway.

So how do I download the latest Sprint release?
The page I am looking at is
http://pathway.sil.org/download/latest-sprint-downloads/
There is a heading at the top:
Latest Sprint — 0.7.9 (August 25, 2011)
but the links near it are about finding the latest stable release.
I want to get the latest *unstable* release.
Also, pls put release date or full version number in each file I can download, so I can tell which ones are newer that what I have installed, 0.7.6.1325, which I downloaded on 6-Jul-2011.
Looking forward to a helpful answer,
Jim
The Latest Sprint page contains all files for the 0.7.9 sprint release of Aug 25, 2011. The very top link on the page is put there for people who do not want the unstable release. If you click on the stable release link, you will go to another page where every download is from the latest stable release.
So all the links on the Latest Sprint release page have the same version number which I think is 0.7.9.1510. I had first posted 0.7.9.1500 at that location but I received a report that the installers for all but the first version had not been generated correctly. I corrected that problem and decided that since all the installers were wrong, I would update them all.
You may be aware that you can subscribe to a feed so that you will receive an email (or a notice in your feed reader) about any new releases. There is an orange release feed icon in the right column of every page.
You can also get more detailed information about releases on the Team city site at http://build.palaso.org You can sign in as a guest and navigate to the pathway section. There are three process there. The first is a daily build. It creates a new BTE version every day there is a change. The second is a continuous build. If any developer checks in code that breaks the build, it will report this fact and send an email to the developer so they can correct it. The third is the sprint build. It builds all the installers that you see on the latest downloads page. The full version number is given there. (The exception might be for this last build where I reran and reposted the latest sprint build after launching the sprint build on the Team City site.)
OK, I am looking for a Pathway SE version which will export to Webonary…. http://pathway.sil.org/webonary/ Any clues on which one to download?
Actually Steve set it up so you didn’t have to go through Pathway to go to webonary. This may change in the future but he wanted user to use the xhtml export from Flex and then import the xhtml and css files into the webonary site directly.
That is a simplification to the process. Thank you…
What Linux pkg(s) do I need to install to test/use the XeLaTex export, please? Websites giving advice on installing Tex varieties are very confusing to someone new to this. I’d like a nice gui along with whatever is needed for printing Scripture, for now; but I want to use XLingPap and print dictionaries later.
I will add the links to the page. We created a package that installs the parts of TeX that Pathway can use. We are still working out the linkage to it. This should be online shortly.
