1 README for Windows Users
2 ========================
4 The following contains some specific comments for people who have
5 installed ASCEND on Windows using the binary 'setup' installer. If you have
6 built you own copy of ASCEND from the source code, comments here may not
7 apply to you.
9 For more information about and support for ASCEND, consult our home page:
10 http://ascend.cheme.cmu.edu/
12 ASCEND documentation (such as it is) is available at the above link, or
13 if you selected to install the Documentation, you should have a link
14 called "User's Manual" in your Start Menu under ASCEND. At present the
15 documentation is available only as a PDF file.
18 Running ASCEND
19 --------------
21 There are two different GUIs for ASCEND. Depending on the software that was
22 available on your machine at the time when you installed ASCEND, you may
23 have either the Tcl/Tk GUI and the PyGTK GUI, or both of these, or neither.
25 The newer GUI is the PyGTK GUI. It looks nice and is under active development.
26 An alternative GUI is the Tcl/Tk GUI which is older but still somewhat more
27 stable and complete than the new GUI. It is not really under active development
28 any more, however. You can choose for yourself.
30 If you've had any problem with getting either of the two GUIs up and running
31 it may be worth reviewing the prerequisites list on our Wiki at
33 http://ascendwiki.cheme.cmu.edu/Prerequisites_for_Windows
35 In some cases, download/install of components may have failed during
36 installation. One know case where this occurs is for people who are using
37 their computer from behind an HTTP proxy. Our current installer is not
38 set up for that use-case, and you should manually install all prerequisites
39 before attempting to install ASCEND.
42 Running the PyGTK GUI
43 ---------------------
45 ASCEND can be launched from the Start menu. If you didn't choose to install
46 the Start menu shortcuts, you can run ASCEND using
48 c:\Python25\pythonw.exe c:\Program Files\ASCEND\ascend
50 The location of 'pythonw.exe' and 'ascend' may be different depending on
51 where you installed Python and where you installed ASCEND.
53 You can also launch the PyGTK GUI for ASCEND by double-clicking on files
54 with the .a4c or .a4l extension. The installer will associate ASCEND with
55 those file extensions.
57 There is not yet a manual for the PyGTK GUI. The 'Help' menu also provides
58 access to the online manual.
61 Running the Tcl/Tk GUI
62 ----------------------
64 The Tcl/Tk GUI can be run from the Start menu.
66 If you didn't select to install start menu shortcuts, you can launch it
67 via
69 c:\Program Files\ASCEND\ascend4.exe
71 The file location will depend on the folder where you chose to install ASCEND.
73 There is no file association for .a4c and .a4l files with the Tcl/Tk GUI.
75 Note that .a4s files are 'scripts' for the Tcl/Tk GUI.
77 A PDF-file manual has been written for the Tcl/Tk GUI and may be downloaded
78 from the ASCEND wiki.
81 If ASCEND Stops Working
82 -----------------------
84 An easy way to break ASCEND is to remove some of the software it depends
85 on in order to work. This includes uninstalling Python, GTK+, Tcl/Tk,
86 PyCairo, PyGObject, PyGTK, IPython, Numpy, Matplotlib and possibly others.
88 The best thing to do in this case is to uninstall ASCEND using the
89 Add/Remove Programs control panel, then attempting to re-install it. At this
90 point, the installer should tell you what components you are missing.
93 Configuration Settings
94 ----------------------
96 There are configuration settings in the Windows Registry that the ASCEND
97 PyGTK GUI uses to determine where its files have been installed.
99 There are also per-user settings installed in
101 c:\Documents and Settings\yourusername\Application Data\.ascend.ini
103 This last file can be edited if you want to add new folders to your
104 ASCENDLIBRARY path, for example if you are building up a collection of your
105 own ASCEND models in a directory of their own.
107 For example:
109 [Directories]
110 librarypath = C:\Program Files\ASCEND\models;C:\Program Files\freesteam\ascend
112 Other settings are also stored in this file. You can delete this file if you
113 to revert to the default settings that ASCEND used when you first installed
114 it.
116 Neither .ascend.ini file nor the Windows Registry are used by the Tcl/Tk
117 version of ASCEND. Instead, a number of files are stored in the 'ascdata'
118 folder within your My Documents folder.
121 Removing ASCEND from your System
122 --------------------------------
124 The uninstaller for ASCEND can be found in the Start menu and also in the
125 Add/Remove Programs list. In any case, the uninstaller will remove all
126 ASCEND components from your system.
128 NOTE however that when the uninstaller runs, it does NOT remove the
129 dependencies such as Python, PyGTK, GTK+ etc that may have been downloaded
130 and installed by the ASCEND installer when you first installed ASCEND.
131 These additional components will need to be removed by you manually. The
132 reason that they are not automatically removed is that it is not
133 possible to determine whether or not you have other programs installed
134 that also depend on them.
136 Syntax Highlighting for TextPad
137 -------------------------------
139 If you would like to be able to edit ASCEND files using a text edit that
140 provides syntax highlighting support, you can use the editor 'TextPad'
141 available from http://www.textpad.com. If you use TextPad, you can use
142 the syntax file 'ascend.syn' that is installed in c:\Program Files\ASCEND
143 by first copying it to your c:\Program Files\TextPad 5\system folder,
144 and then creating a new 'Document Class' for .a4c and .a4l files, and
145 selecting the 'ascend.syn' syntax file.
