i right clicked it and it is executable(.exe im assuming) and it should work but it doesnt.
I just want to make sure this is correct, since nothing really should end in .exe. That is what a windows installer would include. Actually I'm wondering if this is what happened. If you have a windows installer it obviously wouldn't do anything when you try to install it. If it was just not executable I think it will open it as a text file.
So I decided to play around in KDE for a bit and it seems like the way to make something executable is to check a box beneath the boxes for read and write permisions, labeled as "is executable" If it's not checked that could be the problem. As I said, there isn't anything that the installer needs to be run with. Just double clicking will install it as long as it's executable, or maybe it will give you an option to open it as a text file.
You do use the commands that bioalchemist (awesome name by the way) gave you in Konsole, except I think you may already have done the first part in order to even get to the installer. That step is will extract the files from the compressed format that you downloaded them in. Then the second will actually run the installer. I did notice that the extraction command is the wrong file name, but it gives you the idea. Also before you run the installer you'll need to change to the decompressed folder by
If it doesn't work tell us any errors you get after trying to run the installer.
