I'm new here and my question is:
is there a magento file I can Downoad and Upload on my Server and install the magento shop ?
Thanks in advance for your answer
You may download Magento commerce from you Adobe account. I am not sure about Open source version.
But I highly recommend you to install it using composer. Please read https://experienceleague.adobe.com/docs/commerce-operations/installation-guide/composer.html
I was not able to find the file for download :-(
