.NET Framework 4.5.2 Setup has failed

Question

The .NET Framework installer crashes (or at least the following failed message pops up) before even starting to install. On a windows 7 machine without SP1 although I've read this shouldn't matter.

I've tried running as administrator, uninstalling all .NET stuff from the control panel, using the .NET repair tool and the cleaner tool. Have tried both web and offline installer. Nothing helps.

Is there anything else I can try? As it seems to crash before installing, maybe there's a way I can manually extract and start the install?

Update
Have installed SP1 via windows update, but still getting the error. Slowly going through more windows updates/reboots to see if they fix it.

Update
Still no luck. Windows is now stuck indefinitely "checking for updates" and the .NET installer still crashes.

Solution

The Sp1 matters here. The download pages says it requires the Sp1:

Supported Operating System Windows 7 Service Pack 1

You need to install the Windows 7 Sp1 first, otherwise you can't install .Net Framework 4.5.2

Have you run sfc? Use the System File Checker tool to repair missing or corrupted system files

Go to Programs and Features > "Turn Windows features on or off". Are there any Microsoft .NET entries there? If so, try enabling them.

stop WU service, install this update: support.microsoft.com/en-us/kb/3138612 and check again for new updates

[magicandre1981]

any update on the issue? Does the newer WUCLient update fixes the hang? Can you install all updates and now .net 4.5.2?

@magicandre1981 sorry for the late response. The update you suggested worked perfectly and allowed windows update to proceed.

In my case I believe I had installed SP1 already but more windows updates were needed, although not sure which exactly. As per your comment, I had to install https://support.microsoft.com/en-us/kb/3138612 to get windows updates to work.
