We are working on vs 2010 windows 7, 32 bit and the project is running under target framework 3.5.

Now we are implementing credit card process in the website project in signup page.

It’s running fine when running from VS IDE, but after publishing to the local IIS when clicked on signup button, it’s showing this error:

An unhandled win32 exception occured in w3wp.exe The Just-In-Time
debugger was launched without necessary security permissions. To debug
this proces, the JIT debugger must be run as an administrator. Would
you like to debug the proces?

In Application error log im seeing this

Faulting application name: w3wp.exe, version: 7.5.7600.16385, time stamp: 0x4a5bcd2b
Faulting module name: ntdll.dll, version: 6.1.7600.16385, time stamp: 0x4a5bdadb
Exception code: 0xc0000374
Fault offset: 0x000c283b
Faulting process id: 0x3e4
Faulting application start time: 0x01cca60dbfd76d52
Faulting application path: c:\windows\system32\inetsrv\w3wp.exe
Faulting module path: C:\Windows\SYSTEM32\ntdll.dll
Report Id: 126cc4b9-1201-11e1-b3db-003018a9eb5e

It was working fine three days ago from IIS. I do not understand what change caused this issue.

Edited

    I don’t know if your problem had the same cause, but I got this error when trying to debug my app (just pressing F5).

    We got crazy trying to figure why the w3wp.exe was failing with this error when minutes before it was running fine.

    After some investigation we realized that the real problem was in the code of the global.asax: it was throwing an stack overflow exception (pretty ironic for answering here) and that was crashing the w3wp.exe process before VS could attach it to begin debug.

    Fixing the buggy code made the VS to run nicely again.

    I see the question is from long ago, but I hope it helps somebody.
