Windows Update Error Code 643 installing Microsoft .NET Framework 4.5.2

Question

I'm running Windows 7...  I am getting Error Code 643 when trying to install Microsoft .NET Framework 4.5.2.  We've tried everything i can find online, but still no go.  Anyone got ideas?

Answer 1

Update : this method does the trick !!

After the 3 uninstall reboot.

I also update the kb3001652 (Visual studio 2010 update Tools for office runtime)

Don't forget to update also your Pack language of Net framework 4.52 

Then you can reupdate the 3 uninstalled kb.

@MS staff, can you send the problem of these packages? Thanks.

Answer 2

I do use ASC and Norton.  Is this effecting .NET Framework?

Hi Lynden rider,

Thank you for posting your question in the Microsoft Community.

Please answer these questions to get more clarity on this issue:

• Did you make any changes to the computer prior to this issue?
• What are all the troubleshooting steps you have performed on the computer?
• Do you have the Service Pack 1 update installed on the computer?

This issue may occur if the MSI software update registration has become corrupted, or if the .NET Framework installation on the computer has become corrupted.

Sorry to know that you are facing this issue.

For the error code 643, I would suggest you to follow this link and run this fixit to check if this helps.

You receive “0x80070643” or “0x643” error codes when you try to install .NET Framework updates through Windows Update or Microsoft Updates:http://support.microsoft.com/kb/976982

Further, if you do not have Windows Service Pack 1 update installed, then recommend you to install this update. Windows 7 Service Pack 1 (SP1) is an important update that includes previously released security, performance, and stability updates for Windows 7. Installing SP1 helps keep Windows 7 up to date.

I am having the same issue as well.  Online support offered me two types of solutions.  Both involved a cost to fix.  WTH...  Microsoft update installed a Bluetooth driver & tried this update afterwards which failed.  If it weren't for updating the driver, this might not have happened.  They closed the support ticket after I refused to pay their fee.
