Long-time subscriber Richard wrote with a .NET Framework 4 problem I hadn’t experienced, but had read about…
Security Update for Microsoft .NET Framework 4 on XP, Server 2003, Vista, Windows 7, Server 2008, Server 2008 R2 for x64 (KB2804576)
I can’t get the above update to install. I’ve tried everything I can think of (or can do with confidence..!!) including: running Windows Update Diagnostic tool, Microsoft’s NetFix repair tool, down loading the file and trying to install direct (as opposed to Windows auto update), running Microsoft’s PC Helper 360, and trying to install the update in safe mode. I’ve also tried turning off Windows Update Service, deleting the logs, turning the Update Service back on and then trying to install it.
Checking the reported error code 643 doesn’t help. Every time I turn off the computer, it tries to install the update without success.
The only thing I haven’t tried is deleting Net Framework 4 Client Profile (using either Windows add/remove or Revo in Advance mode) and then running Windows Updates again. I’m hesitant to do this as I appreciate some programs require NET Framework 4 to run and I don’t want to ‘mess up’ my computer.
O.S. Windows 7 Professional (x64) Service Pack 1 (build 7601).
Knowing it’s important to install these security updates I hope you can advise. On visiting many web sites researching the problem, I note many others are having the same issue and it’s by no means unique to me.
I wrote back to Richard to tell him that I heard a similar problem from someone else who couldn’t install a .NET Framework 4 update.
The solution that worked for her was to uninstall all the .NET Framework 4 components, reboot, and install it again.
Additional info re trying to install Microsoft .NET Framework 4.
In a follow-up email to Richard, I pointed out that it appears he tried to install .NET 4 over itself, as the log reports "Operation: Repairing" ane the error refers to the "Repair" not succeeding.
If it had been a clean install, I would not expect an error message to refer to "Operation: Repairing" and "Repair did not succeed."
I suggested that he download the stand-alone version of .Net (from the Microsoft Download pages), rather than trying to use the Web Install version or doing via Windows Updates.
- reboot, then
