All cursors are 64x64. They are working on Windows 7. I don't know if they'll work on Windows XP.
To install: - run install.cmd (it probably needs admin permissions, so if it won't work try running it as administrator) - change cursors theme in Control Panel -> Mouse -> Pointers to "Black Arrow"
or
- copy folder "Black Arrow" to \Windows\Cursors - add Black_Arrow.reg to registry - change cursors theme in Control Panel -> Mouse -> Pointers to "Black Arrow"
or change cursors manually in Control Panel -> Mouse -> Pointers
