Cannot install KB2454826 (v2), and therefore IE9 RC. I get an error code 80070057. I know they pulled the update the first time around (I was able to install it) but thought the issues had been resolved. I've uploaded the CBS log to http://cid-eb874ff3c8d7b7ba.office.live.com/browse.aspx/.Public in hopes that someone can give me some guidance. Thanks, -Paul Windows 7 Ultimate (64) with MS Security Essentials 2.0.657

Run sfc /scannow and the System Update Readiness Tool [1] and look if you can install the Update.

André I ran both the sfc /scannow and System Update Readiness tool as you suggested. Both completed successfully without incident. Unfortunately I am still not able to install the failed update - and continue to receive the same error code. I look forward to any further suggestions. Thanks, -Paul

upload the new CBS.log and the checkSUR.log"A programmer is just a tool which converts caffeine into code" CLIP- Stellvertreter http://www.winvistaside.de/

I have uploaded the new files.

Do you have the v1 of the hotfix installed or the update KB2259539? If yes, try to uninstall both updates before installing the v2."A programmer is just a tool which converts caffeine into code" CLIP- Stellvertreter http://www.winvistaside.de/

Unable to uninstall the v1 version of the hotfix or the KB2259539. Both return generic errors indicating "An error has occured. Not all of the updates were successfuly uninstalled".

Run an InPlace Upgrade [1][2] to repair your windows. Your programs are still usable after doing the InPlace upgrade. Now install the update again.

André: The in-place upgrade did the trick. Instead of the individual updates I then successfuly installed SP1. All went well. Still a bit of preference tweaking to do but thanks so much for your help! -Paul

the InPlace upgrade is the last way to reset the Windows and keep all apps. Nice to hear that it worked. Have a nice weekend."A programmer is just a tool which converts caffeine into code" CLIP- Stellvertreter http://www.winvistaside.de/
