Checking if Net Framework 4.8 Is Already Installed

Before you jump into installing Net Framework 4.8, it's worth a quick check to see if it's already there. No point in reinventing the wheel, right? Here’s how you can check:

1. Open PowerShell: The easiest way is to hit the Windows key, type "PowerShell", and hit Enter. Make sure you run it as an administrator. Right-click on "Windows PowerShell" and select "Run as administrator."

2. Run the Command: Copy and paste the following command into the PowerShell window and press Enter:

   Get-ChildItem 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full\' | Get-ItemPropertyValue -Name Release | Out-String
   

3. Check the Output: The command will output a number. This number corresponds to the version of the .NET Framework installed. Here's what to look for:

   • If the number is 528040 or higher, Net Framework 4.8 is already installed.
   • If you see a lower number or nothing at all, you need to install Net Framework 4.8.

This quick check saves you time and ensures you’re not installing something you already have. Now that you know how to check, let's move on to the installation process if needed.

Downloading Net Framework 4.8

Okay, so you’ve checked, and it turns out Net Framework 4.8 isn't already installed. No worries, getting it is pretty straightforward. Here’s how to download it:

1. Head to the Microsoft Website: The official source is always the best and safest. Go to the Microsoft .NET Framework 4.8 download page.
2. Find the Web Installer: Look for the "Web installer". This is usually a small file that downloads the necessary components from the internet during the installation. It’s perfect for ensuring you get the latest version.
3. Download the Installer: Click the download button. Save the file to a location you can easily find, like your Downloads folder.
4. Verify the Download: Before running the installer, it's a good practice to verify the downloaded file to ensure it hasn't been tampered with. You can do this by comparing the file's hash value with the one provided on the Microsoft website.
   • Find the SHA-256 Hash: Look for the SHA-256 hash value on the download page. It's usually listed near the download link.
   • Calculate the Hash Value:

     • Open PowerShell as an administrator.

     • Navigate to the directory where you saved the downloaded file using the cd command. For example:

       cd C:\Users\YourUsername\Downloads
       

     • Run the following command, replacing NDP48-Web.exe with the actual name of the downloaded file:

       Get-FileHash NDP48-Web.exe -Algorithm SHA256 | Format-List
       

     • Compare the hash value displayed in PowerShell with the one provided on the Microsoft website. If they match, your download is safe to use.

Downloading directly from Microsoft ensures you get a genuine and secure copy of Net Framework 4.8. Now that you have the installer, let’s get it running!

Installing Net Framework 4.8 on Windows Server 2019

Alright, you've got the Net Framework 4.8 installer downloaded. Let’s get this show on the road and install it on your Windows Server 2019. Follow these steps:

1. Run the Installer: Locate the downloaded file (usually named something like NDP48-Web.exe) and double-click it to start the installation.
