Understanding the Problem
When you try to install Bijoy Bayanno, you might see an error message stating that Microsoft .NET Framework 3.5 is required. This happens because Bijoy Bayanno was built using this older framework version.
Modern Windows systems (Windows 10 and 11) come with .NET Framework 4.x by default, but they don’t automatically include version 3.5.
Why This Happens
Windows 10 and Windows 11 treat .NET Framework 3.5 as a “Feature on Demand.” This means it’s not installed by default to save space, but the system can download and install it when needed.
The issue occurs when your computer can’t connect to Windows Update or faces problems downloading the necessary files.
Solution 1: Enable .NET Framework 3.5 Online (Easiest Method)
If you have a stable internet connection, this is the quickest way to resolve the issue:
Step-1: Press the Windows key and type “Control Panel”.

Step-2: Open Control Panel and navigate to “Programs and Features“.

Step-3: Click on “Turn Windows features on or off” (on the left panel). Check the box next to “.NET Framework 3.5 (includes .NET 2.0 and 3.0)“.

Step-4: Click “OK” and wait for Windows to download and install the feature.
Step-5: Restart your computer.
Try installing Bijoy Bayanno again. This method typically takes 5-10 minutes depending on your internet speed.
