Switching from 32-bit to 64-bit OS Type/version doesn't work — at Version 1

Description (last modified by )
We inadvertently chose the default "Windows 7" (32-bit) OS type when defining a VM and then installing from a 64-bit Windows 7 .iso file. Windows 7 provided an error message, and we eventually figured out it was because we were running a 32-bit VM for a 64-bit OS. So, in the VirtualBox GUI we switched the Version (os type) to "Windows 7 (64 bit)", and started the VM again with the same .iso file, and the same error message appeared when Windows 7 tried to install.
We then defined another VM using "Windows 7 (64 bit)", used the same 64-bit Windows 7 .iso file to start the installation, and it worked fine. Consequently, I think something is wrong when switching between OS types, at least for "Windows 7" os type and "Windows 7 (64 bit)" -- that it doesn't set up the 64-bit environment properly.

This works now (VBox 4.3.6). The 64-bit capability can also be enabled by 'VBoxManage modifyvm VM_NAME --longmode on'.
