Controle Expert installation stopped because .NET Framework 3.5 is not installed

Question:

What to do when Control Expert installation fails because .NET Framework 3.5 is not installed on the machine?

Answer:

When installing Control Expert, it's essential to have .NET Framework 3.5 installed on the machine. If it’s not installed, the installer will display an error message, causing the installation to fail.

If the machine isn’t connected to the internet, Windows features won't be able to download the necessary framework. However, it is possible to install .NET Framework 3.5 offline using the Windows .iso file.

To do this, open an elevated command prompt and enter the following command:

" DISM /online /enable-feature /featurename:NetFX3 /All /Source:D:\sources\sxs /LimitAccess "

(Note: Replace "D:" with the drice letter assigned to the mounted .iso file on the machine.)

After running this command, a message confirming a successful installation should appear.

Once this is completed, Control Expert can be installed without encountering the previous error.

This method is compatible with both Windows 10 and 11.
