same answer as Tom, unfortunately.. Win 10.. also, Win 10 will not run Pdox 
7 or 8.. unless you have a copy of Pdox 9 or 10 on hand, buying the current 
suite, with 11, right from Corel is usually the only choice now

I wish you luck unless you know someone who has old dusty stock of Win7.
Win7 hasn't been available for purchase for over 2 years. Support for
Win7 will cease (no more security patches) in January 2020. You should
tell them to upgrade to Win10. But be sure you read Woody Leonhard's
advice (on askwoody.com) about which version to install and how to avoid
Microsoft's update madness. If your customer has computers that are
connected to the Internet, and they have Win7 installed after MS support
stops, they're asking for major trouble.
