Issue
You have installed a new version of AutoCAD and when you go to Configure KeySCAPE this does not appear in the drop-down list of available AutoCAD Products.
Solution
With each new release of AutoCAD, we have to rebuild KeySCAPE and KeyTREE to run with this version. This means that your current installation of KeySCAPE/KeyTREE will only support the most recent version of AutoCAD it was built against, plus the previous four versions. Consequently, the Configure dialog will only list the AutoCAD versions it supports, including all equivalent vertical platforms, such as AutoCAD Map and Autodesk Civil 3D.
If the AutoCAD you have installed is not listed in the Configure dialog, please upgrade to the latest version of KeySCAPE or a version that supports your version of AutoCAD.
Note: You will need to run "Configure KeySCAPE" as a local administrator to associate KeySCAPE to run with a different version of AutoCAD.
