Go to Plantronics' Software Download page.

Click on PerSono Audio Control Center.

Then choose your operating system.

You will be prompted to download a self extracting archive, save it to a location of your choice.

Go to the location where you saved the file and simply double click the icon or Select "Run the program from the current location" and then Unzip the program.

You will be given a choice where to unzip the files in this archive, you may select any location you choose.

Once you have extracted the files go to the location you had selected to extract them to then run the Setup.exe and the Install Shield Wizard window will appear.

Follow the instructions for the install then click finish and plug in the headset.

Note: There will be no blue flash screen to prompt you to plug in your headset as there is when you install with the PerSono CD. Also note, if this is a re-installation of the Persono Software you may first be prompted to perform an uninstall of the currently installed version on your system. Once this is complete simply re-execute the setup.exe file to launch the install once the uninstall is finished.
