Installation & Usage

Download a snapshot from GitHub, SourceForge or OSDN and extract it in a location your user has write access to.
Optionally use x96dbg.exe to register a shell extension and add shortcuts to your desktop.
You can now run x32\x32dbg.exe if you want to debug a 32-bit executable or x64\x64dbg.exe to debug a 64-bit executable! If you are unsure you can always run x96dbg.exe and choose your architecture there.

You can also compile x64dbg yourself with a few easy steps!

Without the help of many people and other open-source projects, it would not have been possible to make x64dbg what it is today, thank you!
