Hi Hikerpack my MS.Net Framework 1.1. gives Fatal Execution Engine Failure(0x7927e03e) on the latest update from MS, my lap dell 8200 xp pro refuse's it,my debuger don't work I read we are not the only ones with different problems with 1.1 verison. this first time it will not take update from MS thanks for any help in advance.
After much discussion with MS, including their research group, and to put it simply - the MS.Net Framework update corrupts the OS system. So, you need to reinstall the OS -- now what I did, so as not to lose any data, I reinstalled a clean version of WinXP using a folder name of "WinXP" or anything other than "Windows". Make sure you have enough disk space. Also, make sure that you have the right OS disk -- if you have updated to SP2, then you may need to go buy the latest XPSP2 OS CD.
Before you do, go to your "Documents and Settings" folder and Copy that folder and its contents into another Folder.
You can leave the "Windows" folder alone, create a new account name -- do not use any that you have used before - and then when you boot you will see two OS's; the new one is on top, so use it. Now you have a clean bootup and disable Windows AutoUpdate and DO NOT load MS.Net Framework. You will have to reinstall some drivers, etc and copy your "Documents and Settings" folder into the "new" one so you retain your desktop, favorites, etc. This should all be pretty simple stuff except for your AntiVirus and maybe Spyware programs. You might want to uninstall your AV before reinstalling your OS so the remnants don't interfere with the new installation. That's about it -- I was back up and running within an hour, after being down for almost a week. I just needed to make sure it was a corrupt OS and not something else before reinstalling. Once you are back up, load your AV, etc and then run CleanUp and Defrag to clean everything up.
