Hi Peter,
I manage to download the exe file using the search path. It is a exe file, however when i double click the file it executes but not as a usual installation file. It just shows a progress bar for a split second and that is all. I have tried to install it as a admin but with the same result . The only difference between just double click the exe file or trying to install it as a admin is that when double click, the security dialogue appears. When i accept installation it follows by this quick visual toolbar for half a second and disappears without any installation routine. I have also tried it with the firewall and security turned of, same result.
I have attached a picture of the update history plus a picture of the checksurpackage file so that you can see that i could download it.
From the beginning there was two updates that failed. I could identify one of the fails to be something that had a connection to visual studio 2019. So what i did was to update visual studio because there was a newer version to install. That solved one of the problems. But this .Net 5.0.5 Update for x64 client problem still remains.
I don't know if the last information can give some clue. Maybe it is the Visual Studio that causes the problem, perhaps an uninstall of Visual Studio could solve some problems.
Kind Regards
Pär
