It is a Windows OS message about an un-signed application trying to install on your computer. RME has drivers that are not signed by Microsoft, so they always get that message.
And those RME drivers are perfectly safe!
"Why don't I see the option to select Do not show this again for this app in the security dialog for an unsigned application?
Starting with Java 7 Update 40, the option to select Do not show this again for this app is no longer available. Unlike previous versions a user cannot suppress the security dialog for an unsigned application and will have to select the option, I accept the risk and want to run this app, each time to run the unsigned application.

That is the difference between unsigned applications and signed applications, but not all the time is any application always going to be signed because like WHQL video drivers, not all of them are that way either with beta drivers Nvidia or AMD Radeon may give out.
Nothing wrong with the application if you know where it came from and no risk in installing it, if your anti-virus finds nothing wrong with the file after or during downloading it.
And running JAVA programs on your computer is up to you as to the risk set in the Security section of your Browser you use. That is always up to you and you set the Options in the Browser you use.
The only difference is that the JAVA program is downloaded through your Browser and the Browser setting applies to it, unlike a regular un-signed application which is not downloaded through the Browser but by a Server made to download the program.
But updating JAVA to use in your Browser is a regular normal application like any program to install on your computer, but after the install - running a Java program that is a Browser Java program is through the Browser. Updating Java is not going to do anything except like a fix a security issue much like all the Windows Update Programs - now what - 250 total about since Windows 7 came out.
And Javescript is not a Java program it is a browser type language extension that can be used to add things to a web page, while a regular Java program like a Java game at a website is a Java program and is not Javascript.
http://programmers.stackexchange.com/questions/55104/why-isnt-java-more-widely-used-for-game-development And believe me Javascript is not the Java programming language! I know that for sure having taken Java Programming.
And the only one is usually used is the Java programming language from Sun, the same people who download the updates for your computer, but programming is all together different than running JAVASCRIPT in a Java Virtual Runtime Environment. And Browser usually have the Java Runtime Environment for javascript, not the real java programming language which would become an actual program.
If you ever run into a Java program that wants to install on your computer, you will get a pop-up windows stating that it is a Java program, and then you must decide if it is going to run a-muck or not on your computer should you install it.
On the other hand Javascript runs in a Java Runtime Virtual Environment in your Browser with no message depending on how you have Java runtime set up on your computer or not. The two are not the same. I doubt if you ever ran across a website that wanted to install a java program anyway. I have only a couple of times but still your anti-virus will not help you there, so like always, if you are not sure then why would you install a program you do not trust on your computer?
Javascript is not the same thing as a Java program.
And after all the babbling about it:
