How can I as an administrator without a license provide updates for the users and how can I check if there are any updates available?

You can use the Adobe Remote Update Manager (RUM) to provide the updates. This manager is not suitable for checking the available updates though.

Why do I get the message " No access to applications" when I open Creative Cloud Desktop?

You can only use the Creative Cloud Desktop, if you have installed All Apps package with Self-Service. Other packages (All Apps without Self-Service and Acrobat Pro DC) do not provide access to the Creative Cloud Desktop app. All licensed products are installed here so that you do not have to use Creative Cloud Desktop to use them.

How can I check what package has been installed and if the installation has been successful?

Adobe creates PDapp.log. file during the installation. You can find this file in the TEMP register (Windows: C:\Windows\Temp; macOS: /private/var/root/Library/Logs).

For more information about this file and error codes it contains see:

I am getting an error during the installation process and the installation is stopped. Why? 

It is possible that there are some files of the old installation (with series numbers) left on the computer. Please uninstall the old installation thoroughly. It is advisable to use the Adobe Creative Cloud Cleaner Tool for that. For the tool download and for user guidance please visit Adobe website.

Why do I get the message "Access denied" when after the login on the Adobe website I click on "Download Acrobat DC Pro"?

What happens if I already have a private Adobe account with the e-mail address which is transferred as the primary address?

Can SDL be installed on mobile devices (tablet, smoartphone, etc.)?

No, SDL cannot be installed on mobile Devices. In order to use SDL, the installation-packages that we currently offer must be used, i.e. installation as an app is not complete. Since we can not build installation packages for mobile devices, we can not build this as well.
