Hi there,
Sorry to hear about this issue. CS applications have been discontinued and is no longer compatible with today's operating systems. I am afraid attempts to troubleshoot the install could result in it becoming unusable.
Please take a look at this help article: https://helpx.adobe.com/illustrator/system-requirements-old-versions.html#main_Illustrator_CS4_system_requirements
Also, as Monika mentioned above, as of 9 January 2017 Creative Suite is no longer available for purchase from Adobe. I would suggest that if you can return the product and get your money back. We strongly recommend upgrading your software to a newer version that is supported, that way, we can provide you tech support and access to the latest updates and bug fixes.
Please let me know if you have any questions.
Regards,
Srishti
