As a check, it is best to see if the component is installed in the ossn_components table/database. If it is not there then the issue is not with the component itself. I have installed it 4 times now on a test site and it installs no problem.
the starting point for any install is to see if it is already installed in any form, if it is in a lower version, then it could be causing issues. It is best to have it deleted in any version and install the latest.. I know you have tried like many times, but it is best to see if any previous version is installed and remove it.
It is also a good idea to see if the cache is disabled or if it is then you best flush it before trying it again.
I do not believe it is the component itself as we would all have downloaded the same component, so it can be isolated to something local to your server/site
