Program Compatibility Assistant Warning V5 SR12 on Win7 64

I received a Program Compatibility Assistant Warning running Rhino 3d Version 5 SR12 64-bit
(5.12.50810.13095, 8/10/2015) Commercial on fully updated Windows 7 64.
Would you like any further info for the McNeel software wizards?

Best, Bill

Hi Bill - does this happen every time you start Rhino, or just once? If once, I think it is safe to ignore it as long as Rhino runs as expected…
