If you are willing to install an application or software which requires .NET Framework 3.5 on a Windows Server 2012, Thing can become complicated. You may end up with the following error message.
Another issue is that you cannot just install it by using the offline installer file, that will greet you with another error message like below.
Funny, isn’t it? So if you are facing similar issue and getting crazy then here is the best way to such issue. The prerequisite is that you will be required to have an ISO for Windows Server 2012 media.
You need to mount the media on the server first. After that you can click on the server manager and follow the below steps. (Since I am doing in on my Xenserver I have mounted directly from a storage repository but there are many ways to mount it)
After Mounting the Windows Server 2012 ISO, Launch the Server Wizard, please follow the guide in the video.
