Hi there, thank you in advance for your help on this. I'm running windows 10 inside Parallels on a mac with Yosemite. I have tried installing a new program within Windows and get this message: The function failed because this instance of your program is running inside a virtual machine/hypervisor and you've prevented the function from running inside a VM It doesn't give me any other information than this. Does anyone have any ideas? Many thanks, Jack
