Fusion 7 crash on start

Hi
I had a problem with fusion 7, so I unsinstalled it and I download fusion 8. It seems there are certains components which are not yet included in the software like the Text style. I downloaded the version 7.7.1 again but I have the same probleme as before. When I start the program, when it arrives on the main windows, it close immediatly. I did use version 7 before and then I got the problem after installing K-Codec.
Know someone where could be the problem.
Thanks
David
