Is it necessary to place x64 programs not in the x86 program files

I thought Program Files was somewhat protected. If you put a portable program in there, and it tries to write to its INI file, it could be redirected to Virtual Store, depending on user and permissions.

When I first saw how win7 wanted to split the installation, I didn't like it. My programs are installed in my P:\ (named PROGRAMS) partition. My intent was to have all non win7 system programs installed in the P: root directory, all application name, so I can get there quickly. Now I have gone to making each P:\ program folder before I download the setup zip (or whatever), then putting that in the same folder as I intend the program itself will install. Keeps it all together nicely. Win7 can tell if the application is 32 or 64 bits, and runs accordingly. With Corel paint shop (has both 32 & 64 on CD), the installation itself made the split; made two folders 32 and 64 under my Corel subdirectory. I have had no problems with this approach. Well, perhaps only when program installs misbehave and install on the C: anyway, even after asking.

The OP question is about where to place Portable programs.
Portable programs are NOT installed...
