While VicTsing’s website had a download for software for this mouse, we would strongly recommend not installing it. When installing the software, our computer simply ran the task, without showing a graphic interface, and then disabled mouse clicks on our PC. We tried several mice, and while we could move the cursor, none of them were able to click. Upon rebooting the PC, the software auto-booted on start-up so we had to use our keyboard to uninstall the software. We tried on two different computers and had the same results on each. If you want to reprogram the buttons of this mouse, we suggest using a reliable third-party program.
