  1. Open the Registry Editor on your machine.
  2. Ensure that the following registry key and value exists on your machine so that NintexRPAChromiumChannel.exe can properly launch and allow Nintex RPA LE to communicate with the Nintex RPA Chrome Extension running in Google Chrome. If it does not exist, go to step 3.

    Registry Key: Computer\HKEY_LOCAL_MACHINE\Software\WOW6432Node\Google\Chrome\NativeMessagingHosts\nintexrpa

    Registry Value: This value contains the path to the manifest (JSON file) associated with the Nintex RPA Chrome Extension.

    Name: (Default)

    Type: REG_SZ

    Value: C:\Program Files (x86)\Nintex\RPA\NintexRPAChromiumChannel_Manifest.json

  3. If the registry key and value in step 2 does not exist on your machine, create the missing key and value:
