Bentley does not support its software running on Microsoft operating systems versions that Microsoft has "retired”. Microsoft retired Windows XP in 2014. For more information see Microsoft Support Lifecycle and the Bentley Application Support Lifecycle articles.

• Note: You must have the following Microsoft updates installed on your machine:

  • KB2999226 - For Windows 7 SP1, Windows 8.1, Windows Server 2008 R2 SP1, and Windows Server 2012
  • KB2919355 - For Windows 8.1 and Windows Server 2012

The Prerequisites for Bentley Desktop Applications are automatically downloaded and installed to your workstation while you install Bentley OpenUtilities .

The Prerequisites for Bentley Desktop Applications needs to be installed on your system once, and only needs to be reinstalled if you are installing a later version of Bentley OpenUtilities that requires an updated prerequisite pack.

The Prerequisites for Bentley Desktop Applications is available from the Web Downloads / MySELECT CD area of SELECTservices Online and includes the following components:

1. Microsoft .NET Framework 4.6.2
2. Microsoft Visual Basic for Applications core
3. Microsoft Visual Basic for Applications localized

Microsoft Internet Explorer v11.0 or later with 128-bit cipher strength is also required. It is not part of the Prerequisites for Bentley Desktop Applications.

Copyrights in all components are owned by Microsoft Corporation or one of its affiliates, subsidiaries, or licensors.

4 GB minimum, 16 GB or more recommended.

Additional memory will almost always improve performance, particularly when working with larger data sets.

20 GB free disk space minimum.

This includes space for temporary installation files, product setup packages, required prerequisite pack installation and ~1 GB footprint for Bentley OpenUtilities , and ~300 MB in user data (configuration files, data files, examples, etc.)

Graphics card supported by DirectX 9.0c

See the graphics card manufacturer for latest information on DirectX drivers. 512 MB of video RAM or higher is recommended. If insufficient video RAM or no graphics card supported by DirectX can be found, MicroStation attempts to use software emulation. For optimal performance, graphics display color depth should be set to 24-bit or higher. When using a color depth setting of 16-bit, some inconsistencies will be noted. For more information on recommended workstation profiles for Bentley OpenUtilities , see Microstation System Requirements and Hardware Recommendations.

LDE Integration requires the use of Smallworlds TICS (Transport Independent Client/Server) for communication between server and client.

Note that TICS is deprecated at Smallworld core 4.3 and may not be supported in future Smallworld releases. Effectively, the following Smallworld versions are supported:

1. Version 3.1
2. Version 3.3
3. Version 4.0 Classic or Smallworld Application Framework
4. Version 4.1 Classic or Smallworld Application Framework
5. Version 4.2 Classic or Smallworld Application Framework
6. Version 4.3 Classic or Smallworld Application Framework
7. Version 5.0 Classic or Smallworld Application Framework

500 Mbit/s minimum, 1 Gbit/s or higher recommended

In networking, bandwidth represents the overall capacity of the connection. The greater the capacity, the more likely that better performance will result. Note that the numbers given here reflect actual, not theoretical throughput.

< 5 ms minimum, < 1 ms recommended

Besides Bandwidth, latency is a factor that has a major impact on network speed. The term latency refers to any of several kinds of delays typically incurred in processing of network data. A low latency network improves performance.
