Normally, on Mac, the application initialization error is returned when the APP is extracted from the mounted DMG, however, you don't state in your post that this was done. Can you clarify if you did extract the APP from the mounted DMG?
I'd like to review the online/web installer log files, please upload the 2 log files, Adobe_ADM.log and Adobe_GDE.log saved at ~/Library/Logs/Adobe_ADMLogs (this is the User's Library directory, not the system /Library directory) to cloud.acrobat.com/send using the instructions at How to share a file using Adobe Document Cloud and post the link to the uploaded files in your reply.
In the interim, the offline installer is posted at the bottom of the Installation problems | Flash Player | Mac page in the still having problems section.
I have the same issue as Richard.
Operating System - OS X El Capitan (10.11.3)
Web browser - Chrome 59.0.3071.115 but would love to be able to have Flash on Chrome and FIrefox since I use both.
Program I try to install: AdobeFlashPlayer_26au_a_install.dmg
The Adobe Flash Player Installer starts and I got the 'Application Initialization Error".
In the library logs, Adobe_ADM.log and Adobe_GDE.log do not appear.
I am not an expert in computer science so please explain in details what I should do.
Did you check for the logs in user's Library directory and not system library? Check at ~/Library/Logs and share the same. For Chrome browser, Flash Player comes embedded with the browser and all updates are pushed by Google as part of Chrome updates. If you want to install Flash Player for Firefox, you can use the offline installer available under 'Still having problems' section on Installation problems | Flash Player | Mac page.
Yes I checked the right folder MacintoshHD/Library/Logs and I have no logs from Adobe.
I have a Diagnostic Reports folder and inside Google Chrome_2017-06-29-184442_Laures-MacBook-Pro.wakeups_resource.diag but that's not on the date I tried to install the update for Flash Player (which was July 4th).
Any help is appreciated
Hello, Just got it to work. I saw on Installation problems | Flash Player | Mac page that browser has to be closed to install. I tried it and it worked.
YOUR SYSTEM INFORMATION Your Flash Version
Your browser name
Google Chrome (PPAPI)
Your Operating System (OS)
Then one more question: what is the difference between AdobeFlashPlayer_26ppau_a_install.dmg and AdobeFlashPlayer_26au_a_install.dmg ? Which I install the ppau version ?
Good to know that the issue is resolved!
