# How can I find out in a 32\-bit application what 64\-bit processes are launched?

Documented capabilities of WinAPI do not allow you to directly identify 64\-bit processes from within a 32\-bit program launched in a 64\-bit Windows under WoW64\. In general, reading of memory of a 64\-bit process from a 32\-bit application is impossible due to the difference in address space arrangement\.

You may get a list of 64\-bit processes for a 32\-bit application either by using a specially created 64\-bit process you may exchange messages with or using an out\-of\-process COM server \(for instance, [DLL Surrogate](https://msdn.microsoft.com/en-us/library/ms695225(VS.85).aspx)\)\.
