Operating System   Microsoft® Windows® 98
Microsoft® Windows® 98 Second Edition
Microsoft® Windows® Millennium Edition
Microsoft® Windows NT® 4.0 Workstation (SP 6.0a or later)
Microsoft® Windows® 2000 Professional
Microsoft® Windows® XP Professional
Microsoft® Windows® XP Home Edition

Microsoft® Windows® XP Professional
Microsoft® Windows® XP Home Edition

NOTE: On all these systems, Microsoft® Internet Explorer
5.01 or later and Microsoft® Windows® Installer
2.0 or later are also required
Processor   Pentium 90 MHz*   Pentium III, 1GHz or faster
RAM   32 MB*   128 MB or higher
Video Resolution   800 x 600   1024 x 768 or higher
Plotter   32 MB RAM   64MB or higher**

* Or the minimum required by the operating system, whichever is higher
** The more RAM in your plotter the better, especially for HP plotters. An HP plotter with 32MB of RAM will only be able to process about 8MB of data, which isn't much for a raster image. I don't know why this is, you'll have to as HP where all the rest of the memory goes!

The requirements (excluding video resolution and plotter) are the requirements for the Microsoft .NET Framework, on which this viewer is based. As such, they don't necessarily include enough overhead for a program as complex as this viewer.

The recommendations are based on my personal observations of the computers here that perform acceptably well with this viewer. Almost any computer that you would buy off the shelf or online as of this writing would meet or exceed the recommendations listed above, including those cheap "value computers" most places sell for around $600 - $700.

If your computer is close to the recommendations, but you still find it's performance lacking, check your RAM (this is system memory, NOT hard drive space!). This is the one component that has the single biggest impact on Windows performance in general. Upgrading from less than 128MB of RAM to 128MB or more can breathe a world of new life into an aging computer.
