Hi @Jartymyk Tomas ,
Please check the .net framework version installed on the server first.
And then try to use offline installer.
Best Regards.

Hi @Jartymyk Tomas ,
Windows server comes with .net framework4.7.
If you need to install .net framework 4.0, you can first uncheck .net framework 4.7 in Turn Windows features on or off before installing.
Hi,
I don't need to install version 4.0 because I have version 4.8 installed but applications that use this framework report to me that I don't have any .Net installed I can't remove it from ServerManager because it can't run. I tried to remove via powershell but without success because other services are connected to it. I need to somehow register the .Net Framework so that applications can use it
Hi @Jartymyk Tomas ,
In theory .net framework 4.8 is backward compatible with 4.0, but some applications do need to install 4.0 to run.
