Hello Mauricew,
Sorry for the delayed response and inconvenience caused. AS per the description above, you want to download Adobe ExportPDF on your computer, Is that correct?
The record shows that you have an active subscription to Adobe ExportPDF, It is an online service cannot be downloaded as an application on a computer. But we can access the services through a browser and can be accessed through desktop and mobile app Adobe Reader DC.
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 use the freeware Adobe Reader DC to use the service of Adobe ExportPDF, just "sign-in" with your current Adobe ID and password in Adobe Reader DC. To download Adobe Reader DC, use the URL Adobe - Adobe Acrobat Reader DC Distribution
For troubleshooting, you may refer to Troubleshooting Create PDF, Export PDF, Adobe Send, Fill & Sign … services(PDFPack or Document Cloud Services).
Feel free to update this discussion for any further assistance.
Regards,
Anand Sri.
