ISSUE RESOLVED: this is a Vista permissions/power user issue

SCAgentInterface.dll was not found

SCAgentInterface.dll was not found

Error: “This application has failed to start because SCAgentInterface.dll was not found. Re-installing the application may fix this problem.”

Verify the installation of the Extensis plugin in the “Manage Plugins” in InDesign. There will be a red x beside the plugin that is failing. If you choose “More Info”, you will notice that the error is LoadLibrary failure.

You must be the power user for both InDesign and SuitcaseFusion. Right click and choose “Run as Administrator” when you’re opening the programs. Once this is done, you should be able to open InDesign without error and run the plugin normally.

Everything is working well for me now. Hope this works for you :)
