ControlPoint main installation files can be found at:
C:\Program Files\Metalogix\ControlPoint
Alternatively, and just for a safe measure, you can also whitelist the IIS Virtual Directory, however, please note that there is no executable, dll library or of such. The Directory can be found at:
C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\(12/14/15/16)\TEMPLATE\LAYOUTS\Axceler
On some occasions, it may be necessary to disable the antivirus or security software to allow the installation to proceed since it has to deploy SharePoint solutions and register assemblies in the GAC folder.
*Please note that the file directories might change depending on the version of SharePoint your environment is on.
