Fixing the "The components for the 64-bit debugger are not registered" Error


By hagrin - Posted on 05 January 2010

Recently, on my new 64-bit home development machine, I fired up Visual Studio 2008 for the first time in a while and decided to start cranking out C# solutions to the Project Euler questions. Since I have already completed 14 questions about a year ago, I was able to code a solution to Question #1 very quickly. I decided to debug the solution and ... wham. I received the following error -

Error while trying to run project: Unable to start debugging.

The components for the 64-bit debugger are not registered. Please repair your Visual Studio 2008 Remote Debugger installation via 'Add or Remove Programs' in Control Panel.

To resolve this issue, you will need your Visual Studio 2008 installation disk. On this disk, you will find the following path -

..\Remote Debugger\x64

Inside this folder should be an executable called "rdbgsetup.exe". Run this EXE, open up Visual Studio and you will now be able to remotely debug your projects.
