I have the same problem. I captured the traffic, and it looks like the problem is with the request the installer makes. It is going to the URLs http://22.214.171.124/dlm/fp.gif?type=install&pane=&os=mac&exitcode=-1&app_ver=126.96.36.1997& failed_action_name=&site=live&… and http://188.8.131.52/dlm/ltr.gif?type=install&pane=&os=mac&exitcode=-1&app_ver=5.5&accept ed=N&failed_action_name=&site=…. When I try to retrieve those URLs manually, I get the following message back:
The requested URL "/dlm/fp.gif?type=install&pane=&os=mac&exitcode=-1&app_ver=184.108.40.2067&failed_action_name= &site=live&aih_name=flashPlayer&aih_vers=220.127.116.11&itemid=FP_16_Mac_for_Safari_and_Firefox_ -_NPAPI&abbr=fp&dlc=flashplayer&pre_installed", is invalid.
Why is there no simple offline installer that people can download and use, instead of this complex and fragile system? I get that the update checker needs an online source, but an offline source is a required alternative.
Offline installers for Macs are posted at the bottom of the Installation problems | Flash Player | Mac page, in the 'Still having problems section'. Download the installer that corresponds with the browser(s) you use.
My bad, should have read all the way down to the bottom… What can I say, I'm a guy, I don't read instructions!
So I tried that, but now it tells me that my version is plain 16.0.0, while the current version is 18.104.22.1687. Is it just truncating the version? How can I check?
I had exactly the same problem. I had forgotten that I installed recently an Anti-Virus Security app on my macbook. After deactivating the file system- and web-protection of that app the installation process completed perfectly. Then I activated the protection modules again. Could be a reason. .
All the best from Germany!
Thank you so much it work!!!!!!
