CS6 is no longer available with a subscription

For CS6 back to CS4 you may download ONLY if you bought direct from Adobe via download
-Log-in to your account and click this link https://account.adobe.com/products
--click Order history on the left and then the link to your order that will show on the right
--and finally click the link "Downloads and serial numbers" that will appear
--as always, write the serial number in a text file AND copy that text file and the
---download file(s) to an external drive (or two) to be sure you have what you need
-if you did not buy direct from Adobe via download you must find your original install
--if you have an Education or volume license you MUST use your original media
--the link for an Education or volume license download is not available at all
-if you bought a disc and don't have a drive you will need to buy an external USB drive
-if you bought a download from a 3rd party vendor you will need to contact that vendor

nnattawat, Hello.
CS6 does not work with Catalina due to OS specifications (because 32-bit support has ended). There are no updates.
It is necessary to return the OS to the one before Mojave, but since operation is guaranteed up to macOS 10.9, use at your own risk.

If you keep Catalina, you need to introduce CC.
