Very often, I find the start up error “Just-In-Time-Debugging” after every restart or log off which made me too irritated. In order to solve this error I was slapping myself but I couldn’t find the right solution even online. Finally, my sister has put an end for this fatal trouble. The main cause of this trouble is, if you have installed both VB, DAP (Download Accelerator Plus) it occurs after every restart, and log off. You can solve this trouble very easily because here we have given the finest solution for you without slapping yourself.

Temporary solution for this error is you can switch off your modem in order to avoid this during system start up and you can switch on the modem after the successful sign in, another solution is you can use either VB or DAP to avoid this error.
Permanent solution for this error is :
Rush to Registry by typing “Regedit” in your Run menu and then click ok. Then navigate to the following path and delete the following registry keys.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AeDebug\Debugger HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\DbgManagedDebugger
On a 64-bit operating system also delete the following registry keys: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\AeDebug\Debugger HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\DbgManagedDebugger. Now you can come out of your stress.
Another permanent solution of this error is:
•Go to the Tools Menu and Click Options.
•Select the Debugging Folder from the Option dialog box.
•Select the Just-In-Time page from the Debugging Folder.
•In the Enable Just-In-Time debugging of these types of code box and select or clear the relevant program types: Managed, Native, or Script.
To disable Just-In-Time debugging once it has been enabled you have to login using with administrator privileges. Enabling Just-In-Time debugging sets a registry key, and Administrator privileges are required to change that key.(If you are using Windows Vista, right click on Visual Studio and click run as an administrator for running it)
•Click OK.

I can’t find HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\DbgManagedDebugger
I deleted the other file but after I click “.NETFramework” I can’t find “DbgManagedDebugger” … so I don’t know how to get rid of that file if I can’t find it …
And for the second permanent solution..
I don’t understand where this is:
•Go to the Tools Menu and Click Options.
•Select the Debugging Folder from the Option dialog box.
I clicked Tools Menu on firefox and explorer and then clicked options but I can’t find the DEBUGGING FOLDER from the option dialog box..
HELP !
In AeDebug folder is just “(Default)” and “UserDebuggerHotKey” …what can i do? help pls:)
The error is due to 2 Apache version conflicting with each other.
DO NOT EDIT REGEDIT KEYS if you really do not want to trash your system. Simple way is to uninstall wamp, apache programs
Install the XAMPP. It is pre-bundled with perl, Apache, PHP, mysql, tomcat, mercury, filezilla. installation is trouble free.
