BGB http proxy - Installation operation failed (Internal Error 25001, 80070057)

During a Distribution point and Management point installation on a ConfigMgr site server, I received the following errors in BgbisapiMSI.log and BgbSetup.log
-BGB http proxy - Installation operation failed
-Installation success or error status: 1603
-BGB http proxy - Internal Error 25001, 80070057
-Internal Error 25001, 80070057
-CustomAction CcmRegisterPerfCounters returned actual error code 1603
-Fatal MSI Error - bgbisapi.msi could not be installed

Trick is, you need to have Background Intelligent Transfer Service (BITS) installed on the site server. It is required, otherwise you will see those 25001 errors. After installing BITS and restart SMS_SITE_COMPONENT_MANAGER installation went fine after all. Next time, make sure BITS is installed before starting :-)

Hope it helps!
