All of a sudden, launching a web site in debug mode using Visual Studio 2012 no longer attaches the JavaScript debugger. I have to manually attach to the new Internet Explorer process that launched, and I have to do this everytime that I launch the debugger. I have searched the web all day and have tried numerous things to fix this, and nothing seems to work.

I have tried the following:
1. Resetting my Visual Studio settings
2. Repairing Visual Studio
3. Reinstalling Visual Studio
4. Running the following command:
regsvr32.exe "%ProgramFiles(x86)%\Common Files\Microsoft Shared\VS7Debug\msdbg2.dll

Does anyone have any suggestions? Thanks in advance!

  • Did you check the IE setting: Tools > Internet Options > Advanced tab > In Browsing category > "Disable script debugging" check boxes (both)? Are they unchecked?

  • Yes, both checkboxes are unchecked. I can manually attach to the IE process, but I have to do that every single time. It used to do this automatically. – Sara Sep 10 '13 at 18:55

I have fixed my issue. For reference for others, here are the exact steps I did:

  1. Open Control Panel > Turn Windows features on or off
  2. Uncheck Internet Explorer 10
  3. Click Ok
  4. Restart
  5. After restart open Control Panel > Turn Windows features on or off
  6. Check Internet Explorer 10
  7. Click Ok
  8. Restart

At this point my JavaScript debugging worked again.
