The chipset must support SSE4,1 in order to run 64 bit versions of 4D.
This requirement has existed for a while and is on the certification matrix of
v14, 15, and 16:
{
(1) Instruction set SSE 4.1 must be available if using 64-bit 4D applications.
SSE 4.1 exists in most Intel CPU’s starting 2008.
For details see: https://en.wikipedia.org/wiki/SSE4
}
I know you said you bought the machine in 2008 but maybe it doesn’t actually
support the CPU instruction set, you can check your actual machine with a
program called CPU-Z by CPUID or you can look up the CPU online to see if it
should include the instruction set.

^ It looks like the Optiplex 745 used cPU's from 2006:
