Hi,

Some but not all 64-bit features are available to 32-bit applications

WOW64 provides 32-bit applications with access to some features of 64-bit systems. For example, applications can have more memory up to 4GB with the correct setting. Other features are more limited due to overheads and restrictions. For example, 64-bit Windows will support logical 64 processors but 32-bit applications are restricted to the usual 32 logical processors.

Good luck....
