An idea that MAY work to install and/or run old programs in Windows 10... works for some, not for others
-RIGHT click the program icon or EXE and select a compatibility mode in the pop up option window
-or Run as Administrator http://forums.adobe.com/thread/969395 to assign FULL Windows permissions may help... says Encore, but sometimes required for ALL Adobe programs (this is NOT the same as using an Administrator account)
NOTE - Win10 anniversary update version 1607 has caused MAJOR problems with old programs, so the above may not work
