SFTSequencencer exe Application has encountered with an error

Hi,
Why am I getting this error message when I try to install CRM 2011 for Outlook?
When I clicked on ‘OK’ the sequencer crashed. I have been tried many times to resolve this issue but I could not solve it.
I am confused how to fix it?
Please provide any assistance.
Thanks in advance.
