The problem is the application you are running, not the processor. Applications can detect presence of SSE2 or similar instructions sets and adjust their optimizations accordingly. Your application chooses not to.
So again, this is an issue you should be bringing up with your software provider and ask them why they do not support non-SSE2 hardware.
Is there Amd emulation software for SSE2 ?
I tried http://software.intel.com/en-us/articles/intel-software-development-emulator/ but doesn't work on Amd processors.
For example there are variables:
-no-avx Just emulate AES+PCLMULQDQ+SSE4
-no-aes Just emulate SSE4
-skip-int3 Skip int3 instructions in the execution
I want to just to disable SSE2 at execution of .exe file with such variables.
