Sage 50 Canada

Anyone here able to install Sage Simply Accounting Pro version 9.0 in windows 10? If Yes how did you do it anything you tweak to make it running or added a software for it to run in Windows 10 environment?

If I buy 1 licence for Sage Professional (desktop version), can I open the data for more than one company? (Sage phone support told me that if I have 3 databases that I need to open, I'll have to buy Sage 3 times....) How do I go about buying Sage 50…
