Solved .NET Framework 4 Install, Error code 643

[Dijemon]

I keep trying to install "Microsoft .NET Framework 4 Client Profile for Windows 7 x64-based Systems (KB982670)" Only to get Error code 643.
I have attempted to install in safe boot mode but that did not work either.
Any suggestions?
Thank you.

Hi- I don't know why you're trying to install such an old version of the .net framework but, it sounds to me like your copy of Win 7 isn't up to date. Do you have SP1 and subsequent updates installed?

Wither 2, we meet again.
I'm installing it is because i recently reinstalled windows 7.
Yes, I do have service pack 1 installed, (but i'm not sure what you mean by subsequent updates)

 

[wither 2]

After you installed SP1, did you run the check for updates from the Windows Updates? They should automatically include .net framework updates.

 

[Dijemon]

Yup, done that. All it's showing me is .NET framework 4.

If it's 4.0, I would download and install v4.5.2. from here- Microsoft Update Catalog

Use the one for x64.

Run the check for updates after installing it.

The installation did not succeed, due to fatal error. Here is a copy of the installation log:

I found this elsewhere and changed it for clarity-

1) Run Services.msc

2) Stop the Background Intelligent Transfer Service and Windows Update.

3) Open Windows Explorer.

4) Delete the contents of c:\Windows\SoftwareDistribution\Download.

5) Run the 4.5.2 installation file again.

Does this help?

I've had a nightmare with dotnet just rollback rollback rollback, whether I want to install or uninstall.

Here is what I've done (it might break things);

Found NetFramework folder
"Take Ownership"
Deleted it
Installed the latest .Net
