A new version (
1.4.2) of the Dynamic Components extension was released on
20 October 2016, to support SketchUp 2017 builds, and breaking changes that the 2017 installer makes to the global “
sketchup.exe” browser emulation setting.
If you install SketchUp 2017, and still are running older SketchUp versions, you will need to update those older SketchUp version installs to use the latest version of the Dynamic Components extension.
SketchUp 2017 M0 ships with Dynamic Components version
1.4.2, so you will not need to update it in SketchUp 2017 (until the next DC extension version.)
It is also a good idea, as John Boundy said above, to update the shipped Trimble extensions, for older SketchUp versions, whenever a new major version is released. This is needed as most of these are web-based functions, and the supporting websites often undergo drastic changes, that require the SketchUp extensions to also be overhauled.
