I know the system requirements say that Win10 is required, but has anyone tried to install and run it under an older OS (Win7 is what I'm still using). Sometimes when a software vendor says Win10, they really mean that it isn't supported under older operating systems but can still run on them.

I contacted the customer support to ask this, but it's been a week and no reply.  I would otherwise look at buying Poser11 but not unless I know it'll run first (if there's a trial version of Poser 11 for download, I'd like to at least try that).
