 Welcome back to my YouTube channel. Some people struggle with the installation of the PCRuster tools, plugin and PCRuster. If you have already QGIS on your computer and you have used the OSG4W network installer, you can follow the procedure in this video. Also, if you have used the QGIS standalone installers, the new ones, you will have OSG4W included. You cannot use it if you use the installer with the old dependencies. So you might have multiple versions of QGIS that are linked to a different OSG4W installer. So click right on the QGIS desktop that you always start and choose Open File Location. This brings you here where you can see the shortcuts to QGIS, but you also see the OSG4W setup. Choose Advanced Install and go through the wizard. Then search for PCRuster and you will find it there under Lips and install it. Now this OSG4W installer is related to the installation of your QGIS version that you click in the start menu. It can be that you use another one, so then you need to find the one that is linked to that installation if you have multiple versions. That's very important and that's where it goes wrong when people say that they followed exactly the steps that PCRuster is still missing. Alternatively you can use also Commda for the installation. So now the installation is complete and now I can launch QGIS that belongs to that OSG4W installer. You could also use the shortcut to the QGIS desktop in that OSG4W folder where we have executed the setup because that should also be the correct one. But normally you would use the start menu or another shortcut on your desktop or in the taskbar. And then I can install the PCRuster tools plugin. So you can also of course install this without PCRuster but then you get an error that PCRuster is not installed. So there's a difference between installing the plugin, the PCRuster tools plugin and PCRuster itself. Now we have both and we can find the tools here and they will work. Now if you need more help or you're looking for the documentation go to the PCRuster tools plugin and choose their homepage and this will bring you here where you can find all the installation steps and links to videos and links to documentation and playlists and also where to report your bugs or if you need help.
