You can delete the CHAPI service from Windows through the following methods. CHAPI is required to run Control 5.1+ so this is not recommended except in cases where you are attempting to resolve a problem with CHAPI and a reinstall of the service is required.

Warning - Do not delete CHAPI when users are logged into Control.

1. We must obtain the exact name of the CHAPI service from Windows in order to delete it.
   • Open Control Panel
   • Open Administrative Tools
   • Open Services

1. Find the entry on the list that begins with CHAPI. Keep the Services window open.

1. Open a command prompt in Windows.
   • In Windows 7, click Start then Accessories and right-click on Command Prompt to choose Run as Administrator.
   • In Windows 8, go to Metro Interface and type cmd. A command prompt icon will appear, right-click the icon and choose Run as Administrator at the bottom.

1. Type the following command
   • code

sc delete [service name]

code

• Example:
• code

sc delete CHAPI.ServiceHost_12556

code

1. Click on the Services window you still have open, press F5 to refresh the list of services. If the service still appears (a) wait a few minutes then refresh again or (b) restart the computer.
