W2K SP4 Setup Errors

Using a HP Omnibook 900 with W2K SP2 and downloading W2KSP4 from Windows Update site fails with error dialog box: "Service Pack 4 determined that the following Service Pack 4 files are corrupt:" A list of the corrupt files is shown followed by: If this error persists after you have clicked Retry several times, go to the Windows 2000 Service Pack Web site and select "Problems downloading the Service Pack" This will give you instructions on how to download a version of the Service Pack that does not require a Web connection during installation. Following this instruction and after downloading "Windows 2000 Service Pack 4 Network Install for IT ProfessionalsSP4" from here: http://www.microsoft.com/DownLoads/...F1-749F-49F4-8010-297BD6CA33A0&displaylang=en and executing it, following error dialog appears: "The Microsoft digital signature affirms that the software has been tested with Windows and that the software has not been altered since it was tested. The software you are about to install does not contain a Microsoft digital signature. Therefore there is no guarantee that this software works correctly with Windows. Microsoft Windows Installer...." Clicking the "OK" button another error dialog appears: "The following file in the software package you want to install is not signed C:\DOCUME~1\ADMIN~1\LOCALS~1\Temp\IXP001.TMP\msiexec.exe" Clicking the "OK" button shows another error dialog box: "An unexpected error occurred" and the whole setup process terminates. Similarly happens when trying to update to Internet Explorer 6 SP1 from my existing IE 5.00. As an aside, sometimes a Dr. Watson for Windows 2000 error box appears with the following application Errors: c0000005{00415743} c0000005{00415743} c0000005{00415743} c0000005{00415743} Could it be due to the corrupt msiexec.exe ? or is it some other problems ? Attached are screenshots of the error messages and the svcpack.log. Please help, thanks.

 

Please see if you can get a scan from this free online scanner here. If this fails you could try running a sfc /scannow and a chkdsk.

I'm not familiar with all the shortenings that you use. A more clear help request would have been more suitable.
