TestComplete can't finish installation and stay at installation Wizard window for ever.

Hi All:

    I was facing on TestComplete installation issue two times this afternoon when I tried to install TestComplete version 2.30.1651.7.

    Please see attached screenshot as reference because it looks like freeze at this moment for ever. I got information from EventViewer and it showed following error message:

The program TestComplete_T25169904497.exe version 12.30.1651.7 stopped interacting with Windows and was closed. To see if more information about the problem is available, check the problem history in the Security and Maintenance control panel.

 Any idea why this happened?

Thanks a lot,
