Hi, I got Wine recently (I'm a newbie on Linux, running with Ubuntu), and I tried to install "Faststone viewer", and got this... "The file '/home/great34/Downloads/FSViewerSetup42.exe' is not marked as executable. If this was downloaded or copied from an untrusted source, it may be dangerous to run. For more details, read about the executable bit". What do I need now? Thank you, Mike
