TiaPlus Update Guide ==================== June 2013 This document explains how to update the TiaPlus application on your target machine. Minimum Hardware Requirements ----------------------------- TiaPlus requires a standard IBM compatible PC equipped with (the equivalent of) an Intel Pentium processor (or better), 500 MB RAM, a keyboard and mouse, and approx. 50 MB free hard disk space. A display monitor with a 1024 x 768 pixel resolution is recommended. Software requirements --------------------- TiaPlus can run on Windows 98/98SE/2000/XP/Vista or Windows 7 (32 or 64 bit) operating system. TiaPlus is not tested using Windows ME. It is reported to run normally (but is not fully tested) in a Windows NT4 (SP6) operating environment. The TiaPlus Update requires that the TiaPlus program was running succesfully on your computer before (Visual Basic V6SP6 runtimes, DCOM and ADO support (MDAC 2.5 SP1 or higher) in place). We recommend that your Windows installation is up to date, i.e., that you have installed all available Microsoft Service Packs and patches (using the "Windows Update" facility, for instance). TiaPlus requires the Microsoft Internet Browser (IE5 of higher) installed. ! Please note that Administrator rights (like read, write, modify, execute) are required for folders (directories) that TiaPlus uses, most notably the TiaPlus installation directory (by default C:\Cito\TiaPlus). Update uninstalls old TiaPlus version ------------------------------------- Installing the TiaPlus Update will uninstall (replace) the existing Tiaplus version. The installer will allow you to backup the existing version. Note that installing TiaPlus over an existing version will overwrite the TiaPlus2000.mdb database. If you must uninstall, start the uninstaller via the Control Panel window (Start > Settings > Control Panel), select Add/Remove programs. Do NOT select 'Manual' uninstall. Select 'Automatic' uninstall instead. Manual uninstallation could damage the so called MDAC layer, which is not so easy to repair. TiaPlus Update Installation --------------------------- The TiaPlus installation starts by double-clicking the tiaplus_upd_xxx.exe installer file. Follow the on screen prompts. The default TiaPlus inatallation directory is C:\Cito\TiaPlus. If you change this installation location to another, you may want to edit the TiaPlus database entry for the testset.csv file, in order for the example to work. TiaPlus User's Manual --------------------- After installing you will find a PDF document titled TiaPlus Users Manual.pdf in the Tiaplus installation directory. Print this document and read it carefully before using the application. You will need Adobe Acrobat Reader to do this (see the installation CD or see http://www.adobe.com Starting the TiaPlus program ---------------------------- The TiaPlus application can be started by traversing Start -> Programs -> TiaPlus. Testing TiaPlus --------------- TiaPlus comes with an example input data set containing item answers from 600 persons on 31 Mathematics items. This data set is called 'Testset.csv' and is by default located in the Tiaplus installation directory. Specifications for this data set are available in the file 'Testsetspecs EN.doc' (MS Word document). Note that the TiaPlus database already contains all basic information on these data, so it is possible to have TiaPlus analyze this data right away and look at some results. Feed back --------- After you start using TiaPlus we would very much appreciate receiving some feed back by e-mail to: pok@cito.nl Please send a short message to indicate if TiaPlus is of any use to you, and if you intend to use TiaPlus on a regular basis. Note ---- No software is 100% bug free. You can use TiaPlus at your own risk. Be aware that the use of TiaPlus is restricted to scientific, non-commercial purposes. Currently there are no formal provisions for support from Cito. However, any feedback (bug reports) will be very much appreciated. Please send your E-mail messages to: pok@cito.nl Further updates --------------- Users who are running TiaPlus may want to check the TiaPlus internet web location http://tiaplus.cito.nl periodically to see if a TiaPlus update is available. The name of the EXE file contains the version number, e.g., the file tiaplus_upd_xxx.exe contains all material to install TiaPlus build xxx. Be sure to first rename your current TiaPlus2000.mdb data base file before running the new setup file in case you want to preserve existing item information. ===
