Hi Spider,
Are you still having problems?
I would try downloading the installer again as it may have been faulty the first time.
If it continues, please contact Reallusion Support who will try to help you resolve this issue. They will need to know more about your computer specifications though as without them it's very difficult to say.
Please use the link below to request assistance.
