Do not think so because the component does not effect the backend in any way.
There is an issue with the frontend when the user does not create a menu link, then the Itemid can not be resolved and the modules cannot create the correct links to the component, so the user gets a blank screen when he tries to call the component. But in the backend, even when there is an error during the installation, there won't be any problems in any way.
It seems that your installation was faulty before and the effect you describe is mere chance.
What is the link to you site? Can you switch your site in debug mode? Maybe this helps to find the problem.
