Wondering if these are basically the same thing Vivendi released in 2006? Do these require Dosbox? Will I have any problem running them with 64 bit Windows 7 Ultimate?

Nope, you just have to run the .exe.

They already come with dosbox. Everything is set-up for you, just run the game shortcut on the desktop, or the shortcut in the windows start menu. They run fine in 64-bit, I have 64-bit myself and no problems at all.
