Use the Download link from the PhreePlot homepage or one of the menus. The Win32 version runs on both 32-bit and 64-bit Windows systems. The 64-bit version only runs on 64-bit versions of Windows. It runs slightly faster than the 32-bit version and has access to more memory if available.
You will be asked to accept the License agreement (read here) and will not be able to go any further without doing so. PhreePlot is essentially free to use.
You will then be asked to select an installation directory. By default this will be your Application Data directory, e.g. C:\Users\Me\AppData\Roaming\PhreePlot.
It might be well that you want to change this to something else like C:\PhreePlot. If so use the Browse button to do so. You can create a new directory from there.
It is probably best to make the lowest member of your chosen directory 'PhreePlot', as in the default setting, so that you can remember what is there!
Do not make this directory your Program Files directory.
Three sub-directories will be created below this: system, doc and demo.
You will be asked whether to Associate ppi files with PhreePlot. It is best to take the default (tick yes) because the ppi extension is used for the main PhreePlot input files and this will enable them to be executed directly by double clicking a ppi file in Windows Explorer or similar.
The PhreePlot executable, pp.exe, will always be installed into your Program Files directory, e.g. C:\Program Files\PhreePlot\. You have no say over this. This separation between executable program and program data makes subsequent access easier and safer. The name of the PhreePlot executable is the same for both 32- and 64-bit versions but when run, the version can be seen from the banner on the screen and log file.
Repeat the installation above. It will default to the same user Application Data directory and version sub-directory as before and will overwrite all of the previously-installed files. It will not delete any files that have been added or generated since the initial installation.
There is no need to re-install Ghostscript/GSview, to update the path settings or to reboot.
PhreePlot produces native Postscript (ps) files. Ghostscript enables PhreePlot to make conversions to other formats such as png, pdf, jpg, epsi and eps.
GSview enables you to view ps files directly on the screen. It also uses Ghostscript and can be used to perform an even wider variety of file conversions.
Follow the links on the PhreePlot homepage if you want to download these two programs.
You will have to agree to the license conditions for these programs when you install them. It is useful to associate ps files with GSview.
Neither of these two programs are required for PhreePlot to run but they should help to make your use of PhreePlot more productive.
It is possible to use either Win32 or x64 versions of both Ghostscript and GSview with PhreePlot providing that the paths and settings have been set appropriately.
It is now recommended that the latest version of Ghostscript is used although earlier versions may also work well (see below).
The pdfMaker setting in pp.set is primarily used to locate the Ghostscript executable (e.g. gswin32c.exe) and libraries used in the conversions. If the path given by pdfMaker does not exist, then PhreePlot attempts to find the Ghostscript executable using the GSC environment variable, if defined. If the GSC approach is used, make its value the full pathname but avoid using spaces, i.e. use the shortform such as C:\Progra~1\gs\gs9.10\bin\gswin32.exe.
The path to the PhreePlot exectuable will be automatically added to your Path setting during installation but those for Ghostscript and GSview are not.
Add them using either the Control Panel or the setx.exe program - this comes with Vista/Windows 7 and is part of the Windows 2000 Resource kit for XP. The Ghostscript paths required are something like C:\Program Files\gs\gsx.xx\bin and C:\Program Files\gs\gsx.xx\lib or C:\Program Files (x86)\gs\gsx.xx\bin and C:\Program Files (x86)\gs\gsx.xx\lib depending on the version installed and your operating system. Ghostscript will not be able to produce pdf files without these paths set.
GSview will normally be found under C:\Program Files\Ghostgum\gsview\ or C:\Program Files (x86)\Ghostgum\gsview\, and the path to gsview32.exe (or gsview64.exe) should be set.
Make sure that the PhreePlot pdfMaker setting in the xxxx\system\pp.set file points to the Ghostscript pdf conversion program, the ps2pdf14.bat file. This will provide the path for all of the conversion programs. This is normally something like C:\Program Files\gs\gsx.xx\lib\ps2pdf14.bat.
It is necessary to reboot after changing these settings.
Ghostscript in particular is updated fairly regularly.
The latest version of GSview is also recommended. If a later version of Ghostscript is installed, make sure to update the Ghostscript \bin and \lib paths and the pdfMaker setting in pp.set. Also make sure that GSview is actually using the latest version of Ghostscript (Options | Easy Configure).
You can either do this through the Control Panel or by going to the PhreePlot root folder and executing the uninstaller, unins000.exe. This will remove all the files and settings added during installation but will not remove any that have been added or generated after that.
If you would like to be kept informed of when new updates are available, see the Feedback section of the Home page. You can also do this from PhreePlot by enabling the checkForUpdate setting in pp.set. This will check this server for the latest version at user-defined intervals.
