.NET framework update, won't update

I have a Windows update message that says I need to do the update ".NET Framework 1.1 Service Pack 1 Security Update", but I already have installed 1.1, 1.1 Hotfix, and 3.5 SP1 installed. So I try it anyway (cuz it says I need to) ,but when I try to install the update, after it finishes, I get and error message "Failed - Code 64C (WindowsUpdate_0000064C). But then the update message shows up again. Can anyone help with this? Thanks.

I would try this: go to Add/Remove Programs, and uninstall .NET 1.1 (not 3.x or others), reboot PC, and then go to WindowsUpdate and download & install all available updates.

Alternatively, you could use .NET Framework Cleanup Tool to remove all existing framework versions, and then install .NET 3.5 SP1 full package AND, after that, this update for it.

Normally when you install .NET 3.x, you still need to install 1.1 for applications that use .NET 1.1 because the different versions don't just overwrite and update previous releases as is the case with most other software products. However, the 3.5 SP1 (full release) should include the necessary 1.1 components, so it should be all you need. Just don't forget to patch it afterwards with KB959209 as mentioned.

Good luck.

Are we running Windows Vista? If so its a common problem that I have seen and what Core described will fix the issue.

That fixed it. Thanks a lot.

Question regarding the .net framework 64c error. This error has been going on for months. My computer freezes, crashes with the blue screen of death and is unreliable/unpredictable. Does anyone know if perhaps not having this update installed may be causing my computer freesing problem?

Regarding updates if I get a message telling me to install and update I do it. So my computer should be up to date with patches etc. This .net framework patch is the only one I've ever had a problem.

Thoughts?

Hi, when you get the BSOD what are the details displayed i.e. what is the stop number etc etc.


The BSODs may be nothing to do with .net at all. If you'd like to post the key info displayed on here someone should be able to advise you.

e.g. the error message (if there is one) such as IRQ_NOT_EQUAL
the stop number e.g STOP 0x00000005 (.......
also if any filename mentioned eg atapi.sys
