 Hello, this is Hans van der Kluen's Senior Lecturer at the IHG Delft Institute for Water Education. In this video I'm going to show how to install PCRuster 430. In the past PCRuster had to be installed in a more complicated way, but since PCRuster 430, it can be installed through the KONDA environment, which comes in Anaconda or Mini-KONDA, which I will show in this video. Previously I made a video showing how to install it in Anaconda, with a lot of settings in the environment etc. That's no longer needed, so this video updates the previous ones. Also, PCRuster 430 supports now Python 3.7 and can be installed under Mac, for example. You can find the installation instructions on the PCRuster website, which can easily be accessed through PCRuster.eu. We go to Installation, choose PCRuster 4.3 and there we can see how to install it by clicking on the link. They recommend to use Mini-KONDA because it comes with all the basic stuff that you need. We go to the Mini-KONDA website and in my case I installed the Windows 64-bit version with Python 3.7. After downloading I open the file and I follow the installer. We don't check the boxes for the advanced options because the defaults are okay for us to use. When the installation is completed you click Next. You can uncheck those boxes if you don't want to learn more and click Finish. The site explains that you can find the supported versions of Python by using this first command in the Mini-KONDA prompt. Then it gives us some commands to create the proper environment to go to that environment and then install PCRuster. This last line shows how to install everything in one line. It explains that you have to remove the Python path that were created in previous installations of PCRuster. That's important so we're going to do that first. We click Write on this PC, go to Properties and go to the Advanced System Settings. There we go to the Environment variables. Here we can see the Python path which points to the PCRuster one that we created in the past when we remove it. Then from the Path variable we remove the PCRuster entry. That's okay now. Click OK to close everything. Now let's open the Anaconda prompt from Mini-KONDA. There it is. We're in the base environment and I copy this command. Paste it in here. I also often use GDAL so I add it here. You can add anything else that you need from the KONDA repository. You can even install QGIS here in Anaconda. When you press Enter it starts installing, downloading and installing all these things. The speed depends a bit on your internet network. Once it's done it gives you the advice how to activate the environment. We can type KONDA Activate PCRuster37. That's our environment. To test the installation we can type here PCRCOG which is the old PCRuster language. We can go to Python and say from PCRuster import as to risk. That works. Let's see if GDAL works. That works too. Since we installed Spider as an editor we can also run Spider from here. Type Spider and there it is. Here we can write our scripts. This video explained how to install the new PCRuster 4.3.0 using the KONDA environment in an easy way. You can quickly start using this great tool for map algebra, dynamic modeling, stochastic modeling and data assimilation within Python.
