Installation Problem Cubase 11

I am having trouble installing Cubase 11. I have installed a fresh MacOS Catalina and would like to install Cubase 11 as I did with Cubase 10.5. Unfortunately, Cubase 11 doesn’t have one large setup file like Cubase 10.5 did, but everything separately. Do you have to install everything separately now ??? If so, how to do it? Where are the content folders in my system?

Not to mention the ongoing problem with:

Step 1: FAILED (Updating eLicenser License Database)
Step 2: OK (Repairing Soft-eLicenser)
Step 3: OK (Validating License Usage Periods)
Step 4: OK (Cleaning up eLicenser Memory)
Step 5: FAILED (Recovering License Transactions)
Step 6: FAILED (Sending eLicenser Information)

…and where my Cubase 10.5 license???

Do you have any solution ???
