Windows 10: Why wont my 64 bit system and 64 bit Windows 10 OS install 64 bit software?

Ok so I did a fresh install of a 64 bit windows 10 OS on my new Samsung Pro SSD hard drive. My computer is a Dell desktop 8900 64 bit system. I have confirmed all this in the "About PC" but when I try and install any 64 bit software I get the attached error. Any ideas what is going on? Thanks! Everything else is running fine. I was able to update windows, install other programs etc... Just having this one problem.Note: I installed the new windows from a USB drive I created with the windows media tool. I confirmed the windows system jump drive I created was a 64 bit OS. \

Is there a diffrence between Windows 64-bit OS and Windows 64-bit

Some developer told me that I can run a windows 64-bit system on windows 32-bit. Isn't Windows 64-bit OS and Windows 64-bit the same thing?
