Uninstaller fails on Yosemite 10.10.2 (14C1514)

The uninstaller fails with the following messages:

Running uninstall script:
Calling a shell command: asepsisctl uninstall
=> something went wrong!
Uninstall script finished successfully.

… Except it isn’t successful, as all the .DS_Store files are still visible everywhere, and continue to become visible even after manual deletion.

Can you please provide manual uninstall instructions?
