System Requirements

The .NET Framework

HIMIPref™ 2019 has been built and tested with version 4.8.09037 of the Microsoft .NET Framework. This Microsoft environment must be installed on the client computer; it is generally pre-installed on computers nowadays, but it never hurts to check that it's there! The currently available version is 4.8.1, which may be downloaded from Microsoft.

Operating System

Windows 10 or Windows 11.

Hardware

Any decent laptop or better will be fine. The system I usually use is:

• Processor: Intel(R) Core(TM) i5-1035G1 CPU @ 1.00GHz, 1190MHz, 4 Cores, 8 Logical Processors
• Installed Physical Memory (RAM): 8.00 GB

Networking

Networking has proved to be a problem for some clients. HIMIPref™ calculations require the client-side to wait for approximately five or six 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.
