A 64-bit CPU is required for Player 4.0. The i386 installers are for 32-bit host operating systems, not for 32-bit hardware.
Thanks for the fast answer.
I fine distinction between the 64-bit/32-bit different requirement for (hardware) CPU versus Host OS indeed, I say.
I will revert to pre v4 versions on that old Acer desktop with Athlon 2600+ XP CPU then. Thanks once again.
