Understanding GoldSim Releases and Updates

Product Releases and Updates

GoldSim releases that you can download and install take the following forms:

Version Example Comments
Product Release

11 or 11.0
12 or 12.0

14 or 14.0

Product Releases add major new capabilities to GoldSim. Individual product releases differ in at least one of the first three digits.

"GoldSim 11", "GoldSim 11.1" ,"GoldSim 12" and "GoldSim 14" are considered individual products and can be installed in parallel for simultaneous use.
Product Update 12.1.5 Update 5 to Release 12.1
Product Updates correct problems found in previous releases of the same product. Manuals, Help files and Examples are not changed in Product Updates. Any changes are listed in the release notes. Significant changes may be described in an accompanying Summary Document.

"12.1 Update 5" installs Update 5 of GoldSim 12.1, if it does not yet exist on a computer, or replaces an existing installation of GoldSim 12.1 (e.g., 12.1 Update 4).

Note that previous to GoldSim 11, Product Updates were referred to as Service Packs (SP). Hence, 10.5.1 was referred to as 10.5 SP1.

Build Numbers

Starting with GoldSim 12 any released product release is identified by a unique build number (e.g., 'GoldSim 12.0 #379). The build number is shown in GoldSim's About box and in the details section of Programs and Features (in Windows Control Panel). Typically, users do not need to worry about build numbers as the product release name sufficiently identifies the build (i.e. 'GoldSim 12.0' or 'GoldSim 12.0 Update 1'). However, build numbers provide additional information during beta testing, and in the rare case that a special (interim) release is issued to select customers.

Installation Files

For all release types, the installation file provides a full installation of GoldSim as well as an upgrade installation. While executing the installer on a computer it:

  1. installs the product and updates included in the install for the first time, or
  2. upgrades an existing installation of the product to the update included in the installer.

Example: Executing the installer of GoldSim 12.1.4 installs product "GoldSim 12.1" with Update 4 if and only if no Product Release of "GoldSim 12.1" was present on the PC. If an existing Product Release of "GoldSim 12.1" was present (i.e., Version 12.1 or 12.1.3), the installer would upgrade the existing version to GoldSim 12.1.4. Note that if GoldSim 12 was present (a different Product Release), it would not be impacted (12.1.4 would be installed in parallel to 12).

You can uninstall older product versions of GoldSim that you are no longer using.


Files created using an older GoldSim release can generally be read in by subsequent versions released within several years of the original version (e.g., GoldSim 12 could read a file created in GoldSim 11). However, files created using a later GoldSim release cannot be read in by earlier releases (e.g., GoldSim 11 could not read a file created in GoldSim 12).


All official versions (Releases and Updates) are verified. During verification a large number of test problems are executed and the results compared to expected values.  Verification tests are extensive, but they do not guarantee that GoldSim is bug-free.

Determining Version

From the main menu, select Help | About GoldSim. The version number is also displayed on the splash screen when you first open GoldSim.
