ActiveX files deleted on reboot

I'm deploying Acrobat Reader DC 15.006.30201 via SCCM to about 7000 machines. Acrobat Reader is deployed successfully, the ActiveX files show up in C:\Program Files (x86)\Common Files\Adobe\Acrobat\ActiveX but are gone after the first reboot. If I repair the installation, they come back. This happened with the last version as well. Once the installation is repaired, the issue does not return.

Does anyone have any experience with this? I'd be happy to share more info if you let me know what you need. Thanks!
