KPT5, Photoshop CS5 and Windows 7?

Has anyone up here found out how to use
the plugins of KPT5 with Windows 7 and CS5?
I have been trying to make this work for a long time,
but to no avail.
Thanks!

The clock of life is wound but once,
And no man has the power to tell
Just when the hands will stop
At late or early hour.
Now is the only time you own,
Live, Love, Toil with a will.
Place no faith in tomorrow,
For the clock may then be Still.
