Sensiva Symbol Commander is legacy gesture-recognition software that has been officially discontinued for many years. Because the original developer's website is no longer active, you generally cannot find an official "free download" for modern systems directly from the creator.
| Problem | Solution |
|--------|----------|
| Gestures not detected | Increase “Recognition sensitivity” to 85% in Settings. Also clean your mouse sensor. |
| Program crashes on startup | Run as administrator and disable Data Execution Prevention (DEP) for sensiva.exe: Control Panel → System → Advanced → Performance → DEP → Turn on DEP for essential only. |
| Mouse cursor jumps | Conflicting with Logitech SetPoint or Synaptics touchpad drivers. Add sensiva.exe to the exclusion list in your mouse driver software. |
| No sound on gesture feedback | Sensiva uses legacy beep.sys. Install the “Windows 7 Legacy Audio Beep” hotfix (KB983456 – no longer official, search MajorGeeks). |
| Symbol Commander does not close on shutdown | Edit the registry: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run and add sensiva.exe /exit to a shutdown script via Group Policy. | Also clean your mouse sensor
