Resolution:

control expert 16.2 .net framework 3.5 error

First make sure the .NET framework is installed and active on your machine

Method 1 — Check via Windows Features

  1. Press Windows Key + R
  2. Type:
  3. Optional features
  4. Press Enter
  5. In the Windows Features window, look for:
    • “.NET Framework 3.5 (includes .NET 2.0 and 3.0)”
  6. Status meanings:
    • Checked → Installed
    • Unchecked → Not installed
    • Filled box → Partially installed

Method 2- Check using Command Prompt

  1. Open Command Prompt

  2. Run this command:

    BAT
    reg query "HKLM\SOFTWARE\Microsoft\NET Framework Setup\NDP\v3.5"

If .NET 3.5 is installed, you will see a Version entry like:

Version    REG_SZ    3.5.30729
If it says "The system was unable to find the specified registry key" → It’s not installed.


Method 3- PowerShell Command

Open PowerShell and run:

PowerShell
Get-WindowsFeature Net-Framework-Core

Look for:

  • Installed → It’s on your system
  • Available → Not installed, but can be enabled

Method 4- Check the File System

Look for this folder:

C:\Windows\Microsoft.NET\Framework\v3.5\

If the folder exists → .NET 3.5 is installed.

 

If it is not installed please go to the windows site here:

https://www.microsoft.com/en-ca/download/details.aspx?id=25150

If it is unchecked, please check it. It might ask permission to update and download new files to complete the installation. Please allow it

After it is done, reboot and check the feature again.
