What is my version?

Toolbox is a modular collection of tools, so while that means you can quickly and easily get updates for specific tools, it can be a bit of a chore to tell what version you are currently using. The installer distributes the main part of toolbox that orchestrates the individual tools (the part that gets installed from the Toolbox.exe file). It has its own version that will be updated less often. Its version is specified in the About page (2) or in Windows Control Panel :
1) This name is customizable, so it might say something like "My Company's Tools" here 2) This is where you can see the installer version
You then have the individual tools' versions. Tools come in a few different types and their version is reported slightly differently:
1) Individual tools are the most common type. Their version is specified under the Version column 2a) Combined (Revit split button) tools that come in a single package have their version is specified under the Version column 2b) Combined tools that are from multiple packages but are grouped together logically will be shown as (multiple) and you will have to hover over them and check the individual tools' versions in the tool-tip information 3) Panel tools have their own dedicated panels and so their version is shown in the panel title.
