Installation notes

Installing PhreePlot for the first time

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\Fred\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\ or C:\Program Files (x86)\PhreePlot\. You have no say over this. This separation between executable program and program data makes subsequent access easier and safer in line with Windows conventions. 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. After installation, the PATH environment variable will automatically be set to the installed path.

Installing a more up-to-date copy of Phreeplot

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. If you want to change the installation directory or want to keep the installation directory 'clean', first delete PhreePlot with the uninsxxx.exe uninstaller found in the original application directory and then run the installer. This will not delete any files that have been added or generated since the initial installation.

There is no need to update the path settings or to re login/reboot.

Setting the PHREEPLOT environment variable

This must be set to the application directory, i.e. the directory chosen during installation, e.g. C:\Users\Fred\AppData\Roaming\PhreePlot. This will normally be set during installation.

You can check its value by opening a command prompt and typing 'echo %PHREEPLOT%' which should echo the directory. If it has not been set, use e.g. 'set PHREEPLOT=C:\Users\Fred\AppData\Roaming\PhreePlot (N.B. no trailing \) to set its value for the current session, or use the Settings or Control Panel|System Properties|Environment Variables dialog followed by re-logging in to set permanently.

Installing Ghostscript and GSView

PhreePlot produces native Postscript (ps) files. Ghostscript enables PhreePlot to make conversions to other formats such as png, pdf, jpg and eps. As of 2018, PhreePlot comes with Ghostscript optionally pre-installed but you can install and use your own copy separately.

GSview (Ghostgum) is a separate viewer, also based on Ghostscript, that is also useful. Follow the links on the PhreePlot homepage if you want to download this program.

If installed, it is useful to associate ps files with GSview.

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. The x64 version is recommended if you have a 64-bit PC.

The pdfMaker setting in pp.set is used to locate the Ghostscript executable (gswinxxc.exe) and libraries (gsdllxx.dll) used in the conversions (xx = 32 or 64). If the path given by pdfMaker has not been set, then the internal version will be used.

Uninstalling PhreePlot

You can either do this through the Settings (Control Panel in older versions of Windows) or by going to the PhreePlot root folder and executing the uninstaller, uninsxxx.exe, where xxx is the version number. This will remove all the files and settings added during installation but will not remove any that have been added or generated after that.

Being kept informed of updates

Enable the checkForUpdate setting in pp.set. This will check the PhreePlot server for the latest version at user-defined intervals. See the Guide.
