VS2010 and IE10 Attaching the Script debugger to process iexplore.exe failed

So I am using Win7 x64 with VS2010 and have installed the IE10 Win7 Preview and ReSharper 6.1.

When I attempt to Start Debugging, I receive the following:

"Attaching the Script debugger to process '[1111] iexplore.exe' on machine 'MINE' failed. A debugger is already attached."

I can click OK and look at attached debug sessions - [1111] is grayed out and there is another instance of iexplore.exe with my solution title. I can attach manually and it works fine.

I thought maybe since there were two iexplore.exe pids there would be something wrong, there are not two tabs or windows open and I disabled automatic crash recovery.

Tried this: Attaching the Script debugger to process '[XXXX] IEXPLORE.EXE' on machine 'NAME' failed

Did not work.

Any ideas?

Solution 1:

There is a simpler fix for the JavaScript debugging issue in IE10:

1. Close IE

2. In elevated cmd prompt run this command:

   regsvr32.exe "%ProgramFiles(x86)%\Common Files\Microsoft Shared\VS7Debug\msdbg2.dll"
   

(or %ProgramFiles% on a 32-bit OS)

Solution 2:

The IE10 upgrade resets a whole bunch of stuff. I followed 2 steps to fix this.

1. In IE Advanced settings, under browsing remove the tick on "Disable script debugging (Internet Explorer)"

2. Running this in command prompt (with administrator rights): -

   regsvr32.exe "%ProgramFiles(x86)%\Common Files\Microsoft Shared\VS7Debug\msdbg2.dll

The combination of these 2 and a browser restart of course fixed it for me.

I also agree, the marked solution above of un-installing is hardly a proper solution.

Solution 3:

I have exactly the same problem .. I found a temporary solution but I have to execute each time the same sequence is as follows.

1. Click on the menu "Debug"
2. Click on the "Window" menu
3. Click on the menu "Processes"
4. And right click on iexplorer.exe and "detach the process"

The problem is that every time I have to repeat this procedure every compilation of my project ...
