Welcome to StackOverflow! - /sys/kernel/debug/tracing/options/overwrite - this looks like a Linux path; you probably installed Linux-specific plugins in a Windows installation; remove them and install Windows-specific plugins.

  • I'm guessing this is Android, and the failing Linux path is on the attached device. The OP doesn't actually say so though, so I'm hesitant to add the Android tag. – fadden Jul 26 '14 at 15:22
  • Hi user @user3879701, you should post follow-up questions as a separate question, possibly linking to the previous one in the question body. In this case however I think you should do a clean installation - you don'need to uninstall the current one, you can do it in parallel – Tassos Bassoukos Aug 01 '14 at 06:25

    @TassosBassoukos, the systrace.py tries to read/write the /sys/kernel/debug/tracing/options/overwrite file in the *connected device* not on the host machine. the error OP pasted is due to the lack of support for running systrace on the device. see this [question](http://stackoverflow.com/q/17223244/1523910) for more details. – Avinash R Feb 13 '15 at 08:27
