What are the architecture considerations when using comsvcs.dll to dump a process?

The architecture of the DLL must match the target process. For a **32-bit** process, both 32-bit (e.g., `C:\Windows\Syswow64\comsvcs.dll`) and 64-bit DLLs can be used. For a **64-bit** process, only 64-bit DLLs (e.g., `C:\Windows\system32\comsvcs.dll`) are suitable; using a 32-bit DLL will fail. This is important when targeting lsass.exe (typically 64-bit on modern systems). The winsxs folder contains additional copies of comsvcs.dll for both architectures. Similar compatibility checks apply when using other exploitation techniques.
