Hi, If you are not seeing Premiere Pro app listed for download, it is most likely because of your machine being 32 bit.
Apps will not be listed if your machine does not satisfy the requirements. Check your machine's specs against the Premiere Pro system Requirements.
System requirements | Creative Cloud
Not all apps displayed for download | Creative Cloud desktop app
This shall help.
if you seeing any other issue/error, please respond back.
Regards
Ajay Jain
