[SOLVED] Windows server 2012R2 does not want to install net framework 3.5.

[David86]

Hello. I ask you to help me. I have been trying for several days to find a solution why Windows server 2012R2 does not want to install features as net framework 3.5.
When any user logs into the server, a pop-up message is displayed stating that the 3.5 framework could not be installed. It is not clear what kind of application began to require it.

Spoiler: feature couldn't be installed

Spoiler: add feature fail

There were no known problematic updates that would prevent installation on the server. Specifying the path to the mounted iso with the Winsever 2012 installer also did not help, nor did changing the group policy.

Do you still have the issues posted in this thread ?

Unfortunately, Net Framework 3.5 still does not install even after removing those updates that caused errors in the logs, and Microsoft's recommendations did not help. .NET Framework 3.5 installation errors: 0x800F0906, 0x800F081F, 0x800F0907, 0x800F0922 .Perhaps you have a net fx 3.5 cab file for WinServer 2012r2 EN because I didn’t find it on the disk and the one I found on the net apparently doesn’t fit.
