The 32-bit version of FileLocator Pro will generally run fine on a 64-bit version of Windows but there are a few things to be aware of.
File System Redirector32-bit applications run under what is called WOW64. WOW64 presents a different system32 folder to 32-bit applications than the folder seen in Explorer, e.g. c:\Windows\System32. This is done through something called File System Redirection.
Therefore when 32-bit FileLocator Pro searches the system32 folder on 64-bit Windows it is actually searching a folder called SysWOW64 and this will be different than the actual system32 folder. For more information:
