Good afternoon. I'm having a problem with windows Update and looking for a solution.
Here's the facts:
My computer is 2008 Dell running MS Windows Vista Home Premium 32-bit SP2
I'm trying to run a Windows Update:
Security Update for Microsoft .NET Framework 4 on Windows XP, Windows Server 2003, Windows Vista, Windows 7, Windows Server 2008 x86 (KB2539636)
Update for Microsoft .NET Framework 4 on Windows XP, Windows Server 2003, Windows Vista, Windows 7, Windows Server 2008 x86 (KB2468871)
Update for Microsoft .NET Framework 4 on Windows XP, Windows Server 2003, Windows Vista, Windows 7, Windows Server 2008 x86 (KB2533523)
I've tried to install these updates both individually and as a group. Each time they fail and give me an error code of "00000643."
I visited the Microsoft Support website, searched for the error code and received the following information:
: Windows Update error code "0x643" and Windows Installer error code "1603" are generic error codes. Typically, these error codes mean that the update was not installed. These errors codes are usually caused by a corruption in the .NET Framework installation or by an inconsistency on the MSI database state.
To resolve this problem, you must fix the MSI software update registration corruption issues, or uninstall multiple versions of the .NET Framework by using the .NET Framework Cleanup Tool, and then reinstall those components.http://support.microsoft.com/kb/923100
I'll spare you all the details, but I get very uncomfortable when I read "edit the registry." I've Googled the error code and received other information that is totally different to the steps Microsoft advises.
I know there's no such thing as "one size fits all" but any suggestions on how to to fix this problem would be appreciated.
