Keyframe Animation 2.0 is a major release. We fixed the bugs, added lots of new features, and made it more user friendly.

The main steps are (2017+):
.rbzfile saved to your computer, select the file, and click OK (Microsoft Windows) or Open (Mac OS X).
The last step is important. The first 4 steps copy the plugin to your hard drive. But the files are not loaded until you close and reopen SketchUp. You are still using the old plugin version until you restart SketchUp.
Another good resource is the SketchUp Help Article on managing extensions.
Version 1.9 has a way of recording position data for lots of objects that never actually move. Now the conversion utility cleans this up. It converts the animation from version 1.x format to version 2.0 format for only the moving objects. It deletes the position data for objects that don't move, and removes them from the animation.
As of version 2.0.11, section planes are fully supported! Now you can create object animations, combine them with section plane animations, and export it all to a video. I think this is the only plugin out there that can export both the object animation and section plane animation to a video from SketchUp.
Version 2.0.9+ has a new and improved license management system. It fixed a bug that prevented offline use in version 2.0.1 through 2.0.8. You can once again use the plugin offline for 7 days with a license.
Version 2.0.8+ is compatible with SketchUp 2017. Previous versions might not be compatible with SketchUp 2017 on some computers.
Version 2.0.6 fixed a bug that caused the video export to fail if there were non-ASCII characters in the model's filename.

Special characters are now supported by Keyframe Animation in SketchUp 2014+. SketchUp didn't have support for character encodings before 2014. So, if you are using SketchUp 8 or SketchUp 2013, and there are special characters, Keyframe Animation warns you and fails gracefully.
What is going on under the hood in version 2.0 is so different that your version 1.x animation will not run. Basically, if you open a model with version 1.x position data, all of the commands on the toolbar and menu will be disabled.
However, version 2.0.5+ has a utility that will convert a 1.x animation to the format used in Keyframe Animation 2.x. Access is from the menu item, Keyframe Animation > Convert v1 to v2.
The version 2.x compatible animation is created in a new model. You can save it with any name you want. The original model is NOT modified. When you open the new model in Keyframe Animation 2.0, your old animation will work the same as before, and all the toolbar buttons and menu items will be enabled normally.
This feature requires SketchUp 2014 or newer.
This is the old version of Keyframe Animation. I am not sure there is any good reason to install it, though. Not now that version 2.0 has been fairly well vetted, and has more features, with fewer bug splats, while being more user friendly.
