System Requirements

The .NET Framework

HIMIPref™ 2005 has been built and tested with version 1.1.4322 of the Microsoft .NET Framework. This Microsoft environment must be installed on the client computer and, according to Microsoft, has the following requirements:

Operating System

  • Microsoft® Windows® 98
  • Microsoft® Windows® 98 Second Edition
  • Microsoft® Windows® Millennium Edition (Windows Me)
  • Microsoft® Windows NT® 4 (Workstation or Server) with Service Pack 6a
  • Microsoft® Windows® 2000 (Professional, Server or Advanced Server) with the latest Windows Service pack and critical updates available from the Microsoft Security Web site
  • Microsoft® Windows® XP (Home or Professional)
  • Microsoft® Windows® Server 2003 family

CAUTION:

If you install Dotnetfx.exe on Windows Server 2003 Beta 3, you will break the version of the .NET Framework that is installed with the operating system. Windows Server 2003 Beta 3 installs version 1.0.3215 of the .NET Framework. If you install a later version of the .NET Framework, version 1.0.3215 will be broken. If you install a later version, you can run and use the later version. However, you will not be able to use version 1.0.3215, even after uninstalling the later version.

Hardware

Required

Recommended

CPU

Pentium 90 MHz*

Pentium 90 MHz or faster

RAM

32 MB**

96 MB or higher

Connectivity

Internet Connection

High Speed***

* Or the minimum CPU required to run the operating system, whichever is higher.

** Or the minimum RAM required to run the operating system, whichever is higher.

*** To initialize a day's analysis, the programme sends over 3MB of data and receives about 25MB. This takes about 30 minutes at dial-up speeds; about 30 seconds at high-speed.

Networking


Networking has proved to be a problem for some clients. HIMIPref™ calculations require the client-side to wait for approximately eight minutes for data to be received from the server side. This length of time may lead to proxy-servers and routers dropping or "forgetting" the connection. No problems have yet been observed with direct broadband connections.

To test for potential problems, please use the Browser-Based Connection Test, setting the parameter "tiSleep" to 500 (seconds). The parameter "tiLength" may be set arbitrarily: it has been incorporated in the test in the event that networking technicians wish to check results with varying amounts of data receivable.

The Browser-Based Connection Test has been discussed further on the PrefBlog.com post Connection Test for HIMIPref™. A successful test will result in a browser window like this appearing.
