"Well i think to must use shell to run the installer. open shell go to the directory it is located in and type in the file name i think to must be root to run the installer." That's how I've been running the installer, but I'm under the impression that KDE should recognize that as a .bin file, it is executable and can be run in the same way.
For some reason when I double click on a .bin file (it is an installer) KDE asks me what program I want to use to open it instead of just running it. If I right-click on the icon and look at the properties, the downloaded file has all read/write permissions and the executable box is checked.
