SketchUp comes with a set of Trimble extensions that cannot be totally uninstalled, but they can be switched off so that they do not load if you do not need them.
I myself usually have Advanced Camera Tools, Photo Textures, and Trimble Connect switched off.
When switched off, only a short extension registrar script loads. (This script contains the information that displays in the Extension Manager so that it can be switched on/off, and updated, etc.)
The new v17+ Extension Manager is confusing in that it allows the Trimble “distro” extensions to be uninstalled. This may create an update notification state of confusion.
If you had Trimble Connect ver 2.0.2 installed from the Extension Warehouse, then uninstalled it. Upon next start SketchUp will re-copy the release ver of TC from it’s distribution “staging” folders, which are likely to be an older version. The startup cycle will check the EW for newer extension versions and it’ll find a newer version of TC, and notify you.
The solution is to update the “distro” extensions to the latest version, and switch off those you do not use.
Just leave these extension installed and keep them updated regardless of whether you have them switched on.
The 1st image in the fix doc above shows the list of these (5) native distributed extensions.*
The following image from the User Guide also shows these distributed extensions * …
* The Photo Textures extension has been discontinued (and came with v17 and earlier.)
