i find media sdk can't encode by hardware in 32 bit windows 7 system.

I use  intel media sdk 2017 to realize hardware encoding function,it works well on win7 64 bit computer,but cant work on win7 32 bit. the two. According the requirement,it only has the intel graphic card.

     the 32bit cpu is intel i3 4th processor,the 64 bit cpu is intel i3 6th processor.

so i don't know  sdk surpport 32bit hardware encoding?if surpport,what shoud i do to solve this problem?thanks.
