Find out the processor model taking into account user-mode crash dump

I have a dump for my application. My application doesn’t work for some users, saying "wrong instruction" trying to execute some SSSE instruction that I am there.

In WinDBG, how can I find out the processor model so that I can find out its instruction set and either support the instruction set or update the minimum hardware requirements of the application?

Gets the output !cpuid:

CP  F/M/S  Manufacturer     MHz
 0 16,4,3  <unavailable>   3000
 1 16,4,3  <unavailable>   3000
 2 16,4,3  <unavailable>   3000
 3 16,4,3  <unavailable>   3000

The rest of the google commands say they can help (! Errrec ,! cpuinfo ,! sysinfo) print "Export not found".
