I have just spent two unsuccessful days trying to get Flash to work properly on my HP Pavilion dv7 laptop running Windows 7 Ultimate, Internet Explorer 11.0.9600.16428, and Flash 11.9.900.152. I have gone through the forum (as well as a general Internet search), and did the two recommended checks, and that didn't help. I also do not have the HP Pavilion KB installed that was referenced in another thread on this forum (of course I can't find the patch number right now *sigh*).
- Updating the drivers (Intel HD Graphics Family and Radeon HD 6770M) did not help. Per Device Manager all of my drivers were the latest despite being a couple of years old. However, trying to force the issue by going online through the publishers for updated drivers caused problems with the display (like a mapping mismatch) before then causing a BSoD, which was bad enough to prevent the computer from restarting. I was forced to use a restore point to recover.
- I have a WinXP Virtual Machine on the same system running IE 8.0.6001.18702 and Flash 11.9.900.152 with no problems.
I have rolled Win7 back to IE10 and Flash 11.9.900.152...that did not help, so I went ahead and reinstalled IE11 (KB2841134, which according to Microsoft Updates is the 64-bit version)
- I even installed Shockwave 18.104.22.168 in desperation...didn't help.
- I have uninstalled and re-installed Flash numerous times with rebooting...didn't help.
- I have turned on and off ActiveX Filtering...didn't help.
- I have turned on and off SmartScreen Filter...didn't help.
- Control Panel --> Flash Player (32-bit) --> Advanced shows ActiveX Version: 11.9.900.152, and Plug-in Version: Not installed...is this a problem?
- IE --> Tools --> Manage add-ons provides a possible clue:
-- If both of the two add-ons (Shockwave Flash Object and Shockwave ActiveX Control) are either enabled or disabled, the screen shows white but the audio is fine.
-- If Shockwave Flash Object is enabled and Shockwave ActiveX Control is disabled, the screen also shows white but the audio is fine.
-- If, however, Shockwave Flash Object is disabled and Shockwave ActiveX Control is enabled, the screen still doesn't show video, but the screen is now black, a progress bar and other control icons are displayed, and the buffering "circle" works. (The audio still works fine.) Note that the icons and buffering circle are not as refined as they normally are. For example, the buffering circle is a series of circling dots rather than the full shaded circle (I hope that description is understandable).
Greatly appreciate any insight you can provide!
