Hi,
Thank you for posting in Microsoft Q&A forum.
The error 0x87D01109 means "Failed to verify that the given file is a valid installation package."
1,Please make sure application installation package is not corrupted. Can we manually install the PDF Reader app successfully? If possible, we can re-create the application package to have a try.
2,We can clean the SCCM Cache and reinitiate the download application content to have a try.
Fix SCCM Application Installation Error 0x87D01109
3,If the issue persists, please help check the CAS.log, AppEnforce.log and AppDiscovery.log to see if there is any further information.
Thanks for your time. Have a nice day!
Best regards,
Simon
