Attaching the Script debugger to process '[xxxx] iexplore.exe' on machine XXXXXXXXXX failed. A debugger is already attached.
As you can see the error above. the problem occur when you update your IE from version 9 to 10 in window 7. and then try to debug web application using MSVS2010 .
The Quick solution :
1. Run Command Prompt As Admin
2. Run this script : regsvr32.exe "%ProgramFiles(x86)%\Common Files\Microsoft Shared\VS7Debug\msdbg2.dll
3. Problem Solved.
