Attaching the Script debugger to proces

Answer 1

Here how I fixed this:

Start, run: regsvr32 c:\windows\system32\oleaut32.dll

Answer 2

Make sure you register the dll from an elevated command prompt.

Answer 3

Having exited all instances of Internet Explorer (but not VS), I tried

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

but got an error message LoadLibrary(%ProgramFiles(x86)%\Common Files\Microsoft Shared\VS7Debug\msdbg2.dll) failed - 0x0000007e.

After checking the file system I found the DLL and tried this:

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

which fixed it.

Answer 4

This works but it is:

regsvr32 c:\windows\system32\oleaut32.dll 

not

regsrv32 c:\windows\system32\oleaut32.dll 

Answer 5

I had the same problem, run this command fixed my problem:

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

the key point of running this must start Command Prompt under 'Run as administrartor'
