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

Question

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)

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.

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 ...

I was having the same problem with VS2010 & IE10 (Win7). After weeks of trying to resolve this issue I finally decided to fire up VS2012 to debug my site. I also updated VS2012 to SP1 and restarted my machine and now VS2010 debugging works fine in IE10.

So try installing VS2012 SP1 to fix compatibility issues with VS2010 & IE10.

Someone suggested that running this in an elevated command prompt would do the trick:

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

I tried it and it reported the dll was not found. I searched for the msdbg2.dll and it was not found. It is, apparently, hidden.

I ran:

regsvr32.exe "C:\Program Files (x86)\Common Files\Microsoft Shared\VS7Debug\msdbg2.dll"

and it worked.

This was on Windows 7, 64 bit, VS2010 Premium
