Trying to install astronomy software by right-clicking on exe file and selecting "open with wine windows program loader". this causes the following error: The file '/media/10 09 2008/Windows/setup.exe' is not marked as executable. If this was downloaded or copied form an untrusted source, it may be dangerous to run. For more details, read about the executable bit. I am unable to change the bit because this is a cd file. what do i need to do to install this program? Thank you.
