Error message shown in Visual studio 2010

Asked By 10 points N/A Posted on -


I have an application program for farm solution using the Visual Studio 2010 which is a C# SP 2010 Event Viewer. In the program, it’s a List Item Event and the event source in which, the events are added, updated, and deleted in a regular basis. Why that happened to my Visual studio 2010? Is it ok if I will just get another reinstallation? When I tried executing the debugger mode, a pop-up error appeared. According to the error message, reinstallation is required.

Microsoft Visual Studio

Unable to start debugging on the web server. An error occurred

that usually indicates a corrupt installation (code 0x80040129). If

the problem persists, repair your Visual Studio installation via 'Add

or Remove Programs' in Control Panel.

Why is this happening? I need help for this.

Thank you.

I think it's an 64 bit issue. This message appears when you try to debug an ASP.NET application on a 64 bit OS. So, what to do? Configure your application pool to run a 32 bit working process. 

Now do it: Check the advanced setting for your application pool and set 'Enable 32-bit application' to 'False'

Click 'Ok"

I think your problem has been solved.
