Zend Studio failed to start problem resolution _php instance

I then installed Zend Studio once more to cover the original directory, but still unable to open.
I think that the coverage may not solve the problem, so I put Zend studio to hard-hearted removal, and then installed again.
The result still can't solve my problem, angry me.
So I made the Zend of the setting file of the homemade steel to find out, cut him down, hey ~ sure is the problem of the set file.
To provide you with reference to the reference Bai!!
Solution:
Change the directory name of C:\Documents and settings\user\zde\config_x.x to C:\Documents and Settings\user\zde\config_x.x-old
And then reset and register the Zend Registration code.
