or Run as Administrator to assign FULL Windows permissions may help. RIGHT click the program icon or EXE and select a compatibility mode in the pop up option window Two ideas that MAY work to install and/or run old programs in Windows 10
I do have some help links for that, but as always with old programs and a new OS the 'YMMV' warning applies so I do not know how well things would work for someone trying to do a fresh install on Win10 but I started with Win8.1 and upgraded to Win10 during the free upgrade period. as long as you have a compatible computer and operating system If you have the serial number and either a DVD or download from when you purchased CS6 you may install.
