at 1st time I installed Openfire perfectly. By some reason I uninstall it by Control Panel of Windows7. And I deleted the openfire file manually. I want to install it again. But there is an error shows that : The Java VM could not be started. Please restart the installation. You may use the parameter "/manual"

to download or manually select a different VM.

Log: C:\Users\myname\AppData\local\Temp\i4j_nlog_3

could anybody give me a help ? Thanks a lot.
