What are the negative effects for running a 64bit .NET program from Program Files (x86)?

The reverse of this question. My .NET C# program sets the Platform Target as 'Any CPU', which on my 64 bit Win7 OS, means it will run as 64 bit. Even when the program is stored under Program Files (x86), it will still run as 64 bit interestingly (I…
