Visual Studio supports the debugging of crash dumps from 64-bit applications. Debugging 64-bit crash dumps requires access to a 64-bit machine, either locally or by remote debugging. The following procedures explain how to generate and debug a dump file for a 64-bit application. This will require moving the dump file from the 64-bit machine to a 32-bit machine. Dump files can be quite large, especially if you save the file as Minidump with Heap. Saving the dump file as Minidump without the heap will generate a smaller file, but Visual Studio will not be able to load symbols and debug unless it has access to the binaries.

| Remote debugging is not necessary if you have Visual Studio installed on a 64-bit machine and are able to debug locally. |
To save a dump file for a 64-bit application
-
On the Debug menu, click Attach to Process.
-
In the Attach to Process dialog box, choose the remote machine where the 64-bit application is running, and select the process corresponding to the application. For more information, see How to: Attach to a Running Process.
-
Click OK.
-
On the Debug menu, click Break to break the 64-bit process.
-
On the Debug menu, click Save Dump As.
-
In the Save Dump As dialog box, click Minidump or Minidump with Heap in the Save as type list.
-
Use the navigation controls to choose a save location. This location will be on the remote machine, and the path is as it appears from the remote machine.
-
Click Save.
To load a dump file for a 64-bit application
-
Install the dump file on a 64-bit machine running msvsmon.
-
On a 32-bit machine, launch Visual Studio.
-
In Solution Explorer, select a C++ project.
-
On the Project menu, click Properties.
-
In the Property Pages dialog box, go to the tree control, and under Configuration Properties, click Debugging.
-
On the Debugger to Launch list, click Remote Windows Debugger.
-
Change Remote Server Name to the name of the 64-bit machine with the dump file.
-
In the Remote Command box, specify the path to the dump file.
-
Begin debugging as normal, and the debugger will launch the dump file on the remote 64-bit machine.
