Unable to install .net framework on Windows 7
brucine Posted messages 24389 Registration date Status Membre Last intervention -
Good evening,
I managed to install .net framework 4.5.2 on my Windows 7, but the program I want to install requires at least .net framework 4.6.1. I'm struggling to install the different versions, but I'm always getting the error with the certificate.
I've done some research and tried to update Windows 7 SP1. However, I'm stuck with the update; I attempted to install the update KB310....... but it tells me that it's not the right version of Windows 7, even though I'm on the minimum required version.
I'm going in circles; do you have any idea?
Thank you

Hi,
I didn't understand everything, sorry, but your Windows is not up to date.
Install UpdatePack7R2 and it should work

PS: You need SP1 first
Otherwise, switch to Windows 10, it will simplify things

Hello,
The various "SP2" that can be found here and there are unofficial and only represent the gathering of the roughly 300 updates and bits between SP1 and the end of support.
Even though this has a cumbersome aspect and sometimes hinders a Windows 7 reinstallation due to the considerable number to be processed by Windows Update at the same time, the fact that such an "SP2" has not been installed does not necessarily indicate that Windows 7 is not up to date.
Incidentally, my Windows 7 installation, although it is "SP2", stubbornly refuses to install the monthly update of September 2019 KB4516065 and the infamous .NET Framework update KB4535102 with an error 80092004.
Perhaps it can be noted that, unless circumvented, there have been no Windows 7 security updates since January 2020 and none at all since January 2023.
The error 80092004 is documented as stemming from the absence of SHA2 signed certificates KB4474419 and KB4490628 that need to be installed beforehand; however, the first one is indeed installed on my system.
I haven't tried to install the second one, but in any case, if that is the situation, it is probably necessary to try to find the KBs in question not through Windows Update but through the Microsoft Update Catalog.
https://www.catalog.update.microsoft.com/Home.aspx
More generally, these .NET Framework stories are always a circus; my Windows 7 installation has version 4.8 (KB4503575), which theoretically should support 4.6 for backward compatibility, but it is not excluded that a number of more or less poorly written applications require a particular version.
I was the guinea pig, I quite liked it.
The "SP2" only has real value on a new Windows installation starting from Windows 7 or SP1; otherwise, we assume that updates have been done progressively.
There could also be a corruption in the Windows Update system, but then no updates will work at all, which is another issue that can be addressed separately.
Whatever the situation, a number of updates may fail, either because "SP2" isn't as complete as it claims, or because during its installation some of the 300 updates failed, or because it's simply the case with a traditional update; Windows Update operates on a Russian doll system, the failure of one update can prevent a subsequent one that depends on it, or even result in it not being offered at all.
The simplest approach is to go to the Windows Update history, note the KB of those that have failed, and install them from the Windows Update Catalog starting from the oldest (search for "Windows 7 KBxxxxxx," choose the correct platform x86 or 64, click on the corresponding msu file, and install it by clicking the download).
The outcome is that, despite "SP2," new updates that we had never heard of are offered (and incidentally, even though I'm not doing anything with it, it has nicely installed .NET Framework 4.6, its patch, its visualization, its works, and its bells and whistles...).
