VGEE installer won’t recognise cd- Won’t install Windows 7 in Boot camp

Hi. I put Windows 7 onto an old MacBook Pro 2010. When I come to install VGEE, the installer quits and says it has to be running off the cd (which it is). I suspect it might be because it’s been put on a Mac and bootcamped but is anyone able to help? Yes I know it’s old tech, but I’d like to try to use what I’ve got rather than splash out on any new software… thanks in advance.
