I downloaded the software that I purchased and it does not allow me to open it. I am on Mac OS using a windows 7 (64 bit) virtual machine on virtual box. Once downloaded I try to open it and I receive an error saying it can not be opened and the unzipped file is invalid . I have unzipped it but that does not help me to open and run the software that I have just downloaded. Someone please help me.
