I ran it on Windows 7 x64 without an issue. This will not remove software that has already been installed...for that, go to msconfig. This will just stop the pop ups from the firmware to install whenever the drive is closed.
i too have this drive with this god forsaken blue bird crap. And i can confirm that the tool does not work on vista x64. I have tried running it normally and as an admin. It's still there.
On a side note, the removal tool worked great! Thanks for this.
