Hi All,
We're sorry for the delayed response and inconvenience caused. I have checked the records with your Adobe IDs(email) which you have used to log-in on Adobe forums and found that you are subscribed to Adobe ExportPDF service, it is an online document cloud service and this cannot be downloaded as an application on a computer.
You can access the service through the URL https://cloud.acrobat.com/exportpdf with your Adobe ID and password on a browser like Chrome, or Firefox, or Safari.
You can also access the service through the freeware Adobe Reader desktop application, just sign-in with your current Adobe ID in Adobe Reader.
If you are using Adobe Reader and getting this error, please sign out from Adobe Reader, reboot the machine, launch Adobe Reader and sign back in. Then check for any pending updates of Adobe Reader from help>check for updates, reboot the machine again after updating Adobe Reader.
Try exporting any PDF and check.
For more troubleshooting, you can refer to Adobe article Troubleshooting Create PDF, Export PDF, Adobe Send, Fill & Sign … services(PDFPack or Document Cloud Services).
Let us know if you need any further assistance.
Thanks,
Anand Sri.
