OR for Windows 32-bit, point Windows Explorer to: “C:\Program Files\Cirris\easywire\xHVAC Supply”.
3. Run the installer “USBXpressInstaller.exe” and follow the prompts until completed.
If you continue having trouble connecting to your XHV, try plugging the XHV into a different USB port and wait a moment before restarting Easy-Wire.
