Flash Player Application Initialisation Error

Question

Operating system - Mac OS X El Capitan 10.11.6

Web browser and version – On Chrome as flash installed by default, but Safari 11.1 says no flash installed

Flash Player version – NONE

Was trying to update my flash player, but it wasn't working. Uninstalled it completely, even CS4 Flash in case that was causing issues. Tried to reinstall it, even using the suggested 'offline' version to no avail. Previously, the Install Manager would quit unexpectedly without even properly opening the installer. However, now, even after closing all browsers, I open the package "AdobeFlashPlayer_29_ast_install.dmg", and run the installer, but it comes up with "Application Initialisation Error".

The "Finish" button takes me to the troubleshooting for installation guide but nothing has worked.

I have tried both moving it to the desktop and opening it within the mount. Both have the same consequence.

Here is the crash log for the offline installer: Shared Files - Acrobat.com

Thank you for clarifying and providing the crash log file. The crash log shows Symantec may be interfering with the installation process. Can you please either whitelist the installer in Symantec, or temporarily disable Symantec and try running the offline installer again?

even using the suggested 'offline' version to no avail.

What happens when you attempt to use the offline installer?

For the online installer, that is returning the application initialization error, are you:

extracting the app from the mounted DMG, for example, extracting it to the desktop? If so, launch the application directly from the mounted DMG without extracting it.
using a proxy server? While the online installer should work with a proxy server, sometimes it returns an error. To investigate further please provide the Adobe_ADM.log and Adobe_GDE.log files saved at ~/Library/Logs (user's Library directory, not system Library). Upload the files to Document Clout using the instructions at How to share a file using Adobe Document Cloud or some other file sharing service of your choice that doesn't require account login to access. Post the link to the uploaded files in your reply.
