Wavelab 7 64 bit Version Not working with Windows 10 64 bit

Have the same problem, cannot start Wavelab7 64bit in Windows 10. Downloaded the patch but when I installed it I get the error message and had to roll back. Please see attachment.

According to the error message, a missing pdf file aborted the installation? I have tried reinstalling the 64bit program many time but still get this message on installing the patch. Can anyone help?
