I have been trying for ages to apply the Windows Internet Explorer 9 for Windows 7 for x64-based Systems and get Error details: Code 9C48 even tried IE10 same error. I have run the Windows system update readiness tool, sfc/scannow, several mrfixits, windows update diagnostic etc etc.. IE9 is NOT in my programs list so cannot uninstall, I tried the uninstall using the cmd line and it is still there. When looking at the cbs log I get heaps of error messages about CBS Watchlist Package Missing 0x80070002. It appears lots of people have this problem with updating ie9, my machine is a Dell Inspiron N5110 i7 running windows 7 home premium which came with everything preloaded.
