Downloading ASCEND IV release 0.9 for Windows

Many people have installed ASCEND IV on different windows systems (98, NT, 2000 and XP), and it has worked as it should so we do not expect you to have difficulty with this installation under any Windows operating system. The installation does not use the Windows registry.
1. Register yourself as an ASCEND user, if you haven't already done so, otherwise continue to step 2. Our user support is free, but subject to the demands of our primary research. Most questions are addressed within 12 hours, though the hard ones may take longer. (If your company's firewall will not let you access or submit our registration form please send mail with your name, e-mail address, and reason for interest in ascend to: ascend+register@edrc.cmu.edu.)
2. Click to download zip file (3.8M). Those closer to Europe might find an ftp-only mirror in Portugal but need to keep reading the directions posted here. (If your company's firewall will not let you download from the links above, please try our US ftp site given in step 7 below.)
3. Once you've successfully downloaded ASCEND IV:
   Unpack the zip file with or a similar tool. It will leave you a directory containing two subdirectories, ascend4 and Tcl, and a README.txt file.
4. Locate the executable ascopt4 in the directory ascend4/ascend/bin and make a shortcut to it. Move the shortcut to your desktop or some other easily found place. Start ASCEND by double clicking the shortcut.
5. For additional details on installing for Win311, installing for Win98, obtaining a version containing VC++ 5.0 debugging symbols, or building ASCEND under Windows, see our PC installation instructions .
6. For first-time users, please refer to howto-ascend.pdf Once installed, this version plus its documentation (which you download separately) takes up about 30M of disk space.
7. If your Web browser will not let you access some of the links above, your network service provider has some sort of misguided firewall in place. The work-around is to access the same files by anonymous ftp.

Getting Started Using ASCEND IV For Windows

1. Once you have completed the installation process, double click on the ASCEND startup icon that is on your desktop. ASCEND should start and will place four windows on your screen. The largest reminds you to read our license. It also tells you the version of ASCEND you have and the location in which ASCEND expects to find your user data, \ascdata. The other three are:
   Script, Console, and Library. at this point it may pay to read the documentation. However, if you are impatient, continue.
2. For a quick start, in the Script window, under File, select "Read file ..." Browse into ascend4/models and pick separation_demos.a4s. Using the mouse, highlight all the statements up to and including the first SOLVE statement.
3. Under Execute, select "Statements selected." Watch ASCEND roll into action. When the system stops solving the first model, look at it in the Browser window.
4. If this has convinced you that ASCEND can do something you want, burrow into our HowTos to learn more.
