Why does MapBasic 12.5.1 64-bit install by default to a PATH of C:\Program Files (x86) and not the expected C:\Program Files?

Products affected MapInfo MapBasic™
 
MapBasic 12.5.1 64-bit installs to the 32-bit default PATH of C:\Program Files (x86) because, although this version of MapBasic creates and compiles app's for both 32-bit and 64-bit versions of MapInfo Professional, it is itself, a 32-bit application.
