VS2010出現無法Attach Debug

最近幾天出現這樣的訊息

Attaching the Script debugger to process '[21368] iexplore.exe' on machine 'CLICKAPNB6' failed. A debugger is already attached.

找不到原因, 後來google一下(Attaching the Script debugger to process failed. A debugger is already attached)找到也有人在問

答案是, 到命令模式下

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

就可以deubg了
