WindowBlinds x64 support – The install will not exit.

Hi,
I am running Windows Vista x64, and I can't load WindowBlinds 6 even though it supports Vista x64.
Following is the error message that I am getting. Can anyone help?
Thanks in advance.

WindowBlinds x64 support.
WindowBlinds 6 shareware supports Windows Vista/7 x64 platforms, but does not include support for Window XP/2003 x64.
The install will not exit.
