Resolve PowerPoint 2007 Unable to enter Chinese

Today I did a slide show for a friend, I need PowerPoint, I've been using Microsoft Office 2003 before, but I've upgraded my office to 2007 and I haven't used PowerPoint since the upgrade. Today, the first use of a problem, that is, there is no way to enter Chinese characters in the slide, but the number, English input are very normal. First thought is the input method problem, changed several kinds of input method, but the problem still did not solve.

It turns out that the "Advanced text service" in the Input method setting is turned off.　 I open in the option, PowerPoint can be normal input of familiar characters, hehe. XP above the system this option is open by default, but I used to use the previous Input method controller, this to the disabled, so I met today's problem.
