The ybtlphui.dll file is a piece of Yahoo! Messenger with BT Communicator from Yahoo! Inc.  Messenger is an internet communications program that allows users to chat live across the network.  Messenger also includes protocols to allow other programs to use its service, including British Telecommunications’ BT Communicator.

However, BT Communicator was discontinued in 2006, so the copy of Messenger that includes this file may be obsolete.  An error with the ybtlphui dynamic link library file will mean this program will not work as expected.  To fix this problem you can clean your Windows registry.

Your Windows registry is the information center of your computer.  Windows uses the registry to find and run all the parts of the programs you activate.  When the registry has a problem, the entire system can be affected.  Cleaning your registry will speed up your system and keep away dll file errors.
