When using VS2003 to do the project, often debug the program, but sometimes back to the following problems: "Unable to start debugging, the debugger is not installed correctly, please run the installer or repair the debugger." The first time I met thought it was bad luck, re-use the VS2003 installer to re-repair the tool, you can use. But it ran for a while and appeared like this problem, depressed me for a long time. Because it takes a lot of time to fix this tool, I find the information from the Internet and solve the problem.
The main reason: most of the problems are due to the fact that MDM is corrupted.
Workaround:
Check that the Local service (enter at run: services.msc command startup) has the Machine Debug Manager service, if it is not done as follows:
1, enter CMD at run point
2, then enter the command: CD C:\Program files\common Files\Microsoft Shared\vs7debug
3, re-enter the command: Mdm.exe/regserver
4, then go to the service to see if there is a machine Debug Manager service, if this service is stopped to start.
Restart debugging
