My problem is on .NET Framework 4. I do not know why it suddenly stopped working. I already cleaned up, updated and tried re-installing, but it doesn't work. I am running on Windows XP and I notice that I keep getting the error (code 0x80070643) during installation. What does this means? Somebody please help me on this error. Thank you.
