So I found this over on the Adobe Forums:
Tired of waiting around for Microsoft to issue a Windows update for Flash Player since... well... forever?
Windows 8 ships with Flash Player version 11.3.378.5 while now we're already at version 11.5.502.146! Adobe won't update this ActiveX control if you're using Windows 8, because apparently Microsoft has to release the update themselves. They promised to release such updates frequently, however, it's been many months and not one update had ever been released as of yet.
Here's how you can bud in, get in there, and update the ActiveX control yourself:
- Notice the version you have installed right now by looking at #2 on this page: http://helpx.adobe.c...ash-player.html
- Download the new Flash.ocx files (32-bit and 64-bit) here: http://sites.google....1_5_502_146.zip
- Copy these instructions into Notepad or similar, because you must close all running instances of Internet Explorer right now.
- Go to C:\Windows\System32\Macromed\Flash
- Right-click Flash.ocx and go to Properties.
- Go to the Security tab, and then click Advanced.
- Click Change next to "Owner:"
- Type the following into the box that appeared and then click OK: Administrators
- Under "Permission entries:" double-click "Administrators", check the box "Full control" and then click OK.
- Click OK and then click Yes.
- Click OK.
- Rename Flash.ocx to Flash-original.ocx
- From the ZIP file you downloaded you will see a folder called System32. In there, copy the Flash.ocx file to C:\Windows\System32\Macromed\Flash
- That was for the 32-bit version that gets used. Now repeat steps 3 through 12 for the 64-bit version which also gets used, by replacing all occurrences of "System32" above with "SysWOW64". If you do not find a folder on your computer at C:\Windows\SysWOW64\Macromed\Flash then you actually do not need to repeat the steps for the 64-bit version, because your Windows 8 edition is 32-bit
And PRESTO! Revisit #2 on this page and notice the new version number detected: http://helpx.adobe.c...ash-player.html
Granted; there are version number entries to update in the registry but I doubt that this makes any difference. Best to leave those as-is in case an update finally comes along.
