Hey all. I just figured this out on my own as no one at Adobe will release a playbook that gives proper instructions on this issue. If you are having issues with the application not installing all of the way, you have a permission issue on the the partition where your Yosemite OS is installed. Here is how you fix the issue that you are experiencing:
- Open Disk Utility (press Command and the Space Bar, then type disk utility)
- Locate your disk and the partition where your OS installed.
- Select First Aid (in the right pane next to Erase and Restore)
- Locate the button "Verify Disk Permissions" and click on it.
- Wait, get some coffee and relax, this will all be over soon
- When Verify Disk Permissions is complete, click on the button "Repair Disk Permissions"
- Now grab breakfast, lunch or dinner and tell someone you love that you love them.
- After your disk permissions have been repaired, close out Disk Utility
- Open the FlashPlayer installation file and run the installation again.
- Finally, whew... Enjoy your entertainment fare. You made it across the schism that Adobe loves to plague their loyal patrons with.
I hope this helps someone. Let me know if it worked or didn't; I am curious if you all will see the same success that I have realized.
Cheers & Many Regards,
Geoff
