Programs not shutting down correctly

I'm getting application error messages when I close non-
system programs, such as Musicmatch Jukebox, Dr.TagPlus,
PCDJFX, and so on. These messages refer to memory at one
location that is at another location and cannot
be "written" or "read". In some cases references to
illegal instructions. Once again refering to separate
locations.
For example: pcdj.exe Application error
The exception illegal instruction
An attempt was made to execute an illegal instruction
(0xc000001d) occurred in the apllication at location
(0x00d1f0c2) Click OK to terminate program.

The programs seem to function well while I am using them,
but the fact that they do not shut down correctly has me
concerned.

Is there anyone out there with knowledge as to what could
be causing this and what I can do do fix it.

I would really appreciate any help that anyone could give
me.

Thank You
