bloom Depending on the edition you installed, there are typically "Allow executing file" options accessible via the file properties. Universally you can use a Terminal to just do
chmod +x on the file. Google is your friend here.
For supporting libraries, you'll need to run it from the Terminal, see if it's missing any libraries, and install them.
eopkg search and
eopkg install will get you there assuming we have the library in the repo, but we're not going to be able to help you without logs.
