Thanks for reaching out. I am afraid you have only 4GB of memory on your machine. Minimum required is 8GB and recommended is 16GB. I'd suggest upgrading your memory as recommended.
Please find more information about system requirements of Adobe Illustrator on this help article.
Hope it helps.
so I will not install illustrator? but it says on system requirements 1gb of ram for 64 bit
Thanks for responding. Are you trying to install an old version of the app?
