Windows   Windows – .NET Framework 4.7.1 install stuck / hangs

I needed to install .NET 4.7.1 to allow updating Exchange 2013 to CU 21.
This is the installer I downloaded and tried to install:

But the installation never ends. It remains stuck without progressing in the “Installation progress” bar. Tested both with offline and online installation:
Windows - .NET Framework 4.7.1 install stuck hangs

To install .NET Framework 4.7.1 download the msu package from the following link:

Windows - .NET Framework 4.7.1 msu packages install succesfully

It seems that there is some kind of problem with the other format, but the msu worked correctly for me.

Update – For Windows Server 2016 (Thanks to Ryan comment):
If running into the same issue when installing CU10 for Exchange 2016 the msu of .NET 4.7.1 for Windows Server 2016 here it is:

  1. This happened to me too. No progress showing. However, I looked at the process manager. The install was using cpu and memory and the number was going up and down. Also, the event viewer was showing events in the Application section, so I just let it sit. It took over an hour but it did finish.

  2. I also ran into this, but as others, I waited, as the process manager showed aorund 25% cpu load on the .net setup installer.
    Waited 25-30mins, and after that, it was installed ๐Ÿ˜‰
    But I admit, it just stands there as stalled, but it does actually process, as you can see on process manager ๐Ÿ˜‰
