I have difficulties installing the latest version of Adobe Flash Player (18.104.22.168) on my Mac OS X 10.9.3 (Mavericks). Every time I do so, it fails at 90% with the following error message.
Error: Unable to proceed with the installation
When I go to troubleshoot the problem, I find that I have version 22.214.171.124 of Flash Player installed on my system, and that the (alleged) latest version (for Mac OS X 10.6, 10.7 and 10.8) is 126.96.36.199 (see following URL).
Further research has revealed that the latest version of Flash Player (for Mac OS X 10.6, 10.7, 10.8 and 10.9) is 188.8.131.52 (see following URL).
This is not the first time I have experienced problems upgrading Adobe Flash Player. I experienced a similar problem before upgrading to Mac OS X 10.9 except with different version numbers of the same software. That is, the version that was installed was greater than the version that was downloaded. Note that I did not experience this problem with prior versions of the OS (i.e. Mac OS X 10.6 and 10.7).
This time I went one step further and used a different default browser to locate, download and install (what I presumed was the latest version of) Flash Player. No difference....
My question is, why does my default browser point to an older version of the installation software, and how can I resolve this? Also, correct me if I am wrong but, the reason I have a 'later' version of the software (that is, version 184.108.40.206) is due to the OS upgrade? I do not recall ever upgrading Adobe Flash Player....
Not sure whether or not this is relevant, but I also have Adobe Creative Suite 5 installed on my system (which was also successfully upgraded during all OS upgrades).
UPDATE: Did a bit more searching on the Adobe forums and found a link to a previous version of Adobe Flash Player version 220.127.116.11. Although not the latest version, I have successfully installed it. That is, after I uninstalled the older version of Flash Player. The problem I experienced sounds almost identical to this installation problem.
I am still, however, experiencing the same problem when upgrading to version 14 of Flash Player (even through System Preferences). Seems to be a problem with the installer, and not my system configuration since, to resolve this problem, I uninstall Flash Player (like before) and successfully installed Flash Player version 14 OS X, which I found and downloaded from the same web site. Note that all attempts to use the install program that updates Adobe Flash Player have failed.
UPDATE 2: It appears that the problem I described is a known issue regarding installing Flash Player on OS X 10.9 using the shim installer from get.adobe.com/flashplayer. For further details, see the following thread from the Adobe Forums.
