Hi there, I edited your topic title and took out the shouting.
1.5. Use a proper topic title.
You must use a proper topic title. It must be, like rule 1.3 explains, all in lower case, except for the first letter of each word, which may be in upper case. Additionally, you must describe what the topic is about using some key words or a small sentence.
It’s not a big deal, just refrain from doing this, as Eclipse has a helpful community that will assist you with your question, whether you type in all caps or not.
Like Admiral pointed out, this looks like an issue with the library files. If I may add to his link, make sure you run it as administrator, as some files won’t be registered, depending on your settings and your operating system.
