Programmatically determine whether Reader or Acrobat

[abc5C2F]

My application programmatically determine whether reader or acrobat by this way.

・Acrobat

¥¥HKEY_LOCAL_MACHINE¥SOFTWARE¥Microsoft¥Windows¥CurrentVersion¥App Paths¥Acrobat.exe

・Adobe Reader

¥¥HKEY_LOCAL_MACHINE¥SOFTWARE¥Microsoft¥Windows¥CurrentVersion¥App Paths¥AcroRd32.exe

But when I installed the latest  64 bit reader,  I find its registry info is same as the acrobat.

How can I determine the latest reader, Thanks.

They are the same app, from what I can see. Not two different copies, they are exactly the same app. They check license info to decide which product they are today.
