When trying to install a CCP created software package, the installation fails in Acrobat with return code 19.
The PDApp.log shows the following errors:
The return code from the Adobe Installer Process is (19).Stopping the installation process.
Failed in Acrobat [Package Path to Acrobat] deployment (3145775).Stopping the installation process.
Return code 19 indicates that a conflicting process is running.
Close the conflicting processes and try the installation again.
To identify the conflicting process:
