Can't install the component

Acutally I'm not a new costumer. But I purchased a new subscription without being logged in to my account and now I had to creat a new one in order to be able to download my purchase. However: I can't install the component and this is the first time I'm facing such an issue. Background: The component was running on the site before. The site was hacked some time ago. Everything was deletetd despite the database which was clean. Today I started to rebuild the site from zero, connected joomla with the old database. Now, that I want to uploade the component, I get the attached error.

Thank you very much for your advice.
