You will need to create an account to download the software, I have direct links to the software however, it is best that you visit the CodeSys store yourself & set up an account to make sure you get the latest version in case they come out with an update.

I do not recommend downloading files from anywhere but the actual business that makes the software so we are not responsible if you choose to use the links below.

Installing CodeSys Development System Software


After you have downloaded the software, copy it to where you would like the software to be used. In my case, I moved this to my Virtual computer & also my host computer so I had two places to use the software.

Once you have it on the computer you want to use the software on then right-click it then run as Administrator.

Run CodeSys Install As Admin


This will then extract the files needed for the proper install as shown below.

Note that the framework for Windows may need to be installed, it is dependent on what operating system & updates you have. If the frame works install starts right after this, allow it to run & then allow your system to reboot if needed.

This is detected from system scans of the Windows system & could run but also may not run due to the state of your computer’s operating system.

The next thing that should appear is the Welcome message for the install start.

At this point press the next button to start the install process.

You will now see a screen asking what type of install you would like to do, I choose the custom install on any software I download from the internet because I want to make sure there are no hidden files like McAfee or Norton.

Pick Custom then press the NEXT button.

Then a custom setup screen will appear, press the drop-down on the CODESYS top-level to verify there is no other software being installed.

Note: As of 04-26-2021, I have verified that the install file is clean & from research, CodeSys has no plans of added any third-party software so all should be good.

Press the NEXT button to continue the install.
