@kovidgoyal,
Thank you very much for the technical tip regarding Windows child processes. Following your advice, I've updated the plugin to version 1.2.1.
Now, before launching the installer, the plugin uses taskkill to clean up any remaining instances of ebook-viewer.exe, ebook-edit.exe, and calibre-parallel.exe. This ensures the .msi installer doesn't run into "files in use" errors. I've also kept the --shutdown-running-calibre command to ensure the database closes gracefully first.
Thanks for keeping an eye on this!
I'm learning a lot from the comments.
