A popular tool for reversing, auditing, and analyzing 64-bit binaries.

Extract only the icons or manifests from a bloated Microsoft DLL and rebuild a minimal resource-only library.
One of the most beloved features of the classic PE Explorer was its Resource Editor. In a modern 64-bit iteration, this tool allows users to view, extract, modify, or replace resources embedded inside 64-bit binaries without recompilation. This includes: pe explorer 64bit version 2
While not a full IDA Pro alternative, the disassembler:
The original PE Explorer was legendary for its UPX Unpacker and Resource Editor . However, modern malware and software development rely almost exclusively on 64-bit code. PEExplorerV2 (and other community projects like adamhlt's PE-Explorer ) focuses on , allowing security researchers and developers to peek inside a file without ever executing it. Alternatives for 64-bit Editing
The "Rich Header" is an undocumented, undocumented block of data found in binaries compiled with Microsoft Visual Studio. It contains metadata about the specific compiler versions, build numbers, and tools used to create the application. A modern PE tool must decrypt and parse this header, as it provides invaluable attribution clues during cyber espionage and threat group investigations.

When you load a 64-bit binary into the new PE Explorer, it attempts to identify standard API calls. In a 64-bit environment, this is harder than it sounds due to the way the x64 calling convention works (fastcalls using registers like RCX , RDX , R8 , R9 ).
Unlike the legacy tool, this version fully supports both x86 and x64 Portable Executable (PE) files. Comprehensive Parsing:
Inspects high-entropy 64-bit ASLR flags. In a modern 64-bit iteration, this tool allows
64-bit binaries replace the stack-based frame pointers of 32-bit platforms with table-driven SEH. Version 2 includes an integrated Exception Directory viewer to map runtime unrolling behaviors. 2. Core Functional Modules inside PE Explorer v2
In the classic PE format, certain structures were rigid. Moving to 64-bit required expanding the Optional Header (ironically named, as it is mandatory) to accommodate 64-bit memory addresses. The old PE Explorer v1.99 would choke on this. It would misalign the section headers or fail to parse the newer resource directories, crashing or displaying garbage data.
Part of the Explorer Suite developed by Daniel Pistelli, CFF Explorer was one of the first tools to fully embrace the x64 architecture.
