problems caused by flash add- ins
Workaround: Verify that the Flash add-in is installed and enabled IE9.
First step, open IE9, click the Tools icon, click Manage Add-ins, and select all add-ins in the Show Drop-down box.
Step two, and then in the list on the right, see if there is an add-in with the name Shockwave Flash Object and show enabled.
If you do not find the add-in to indicate that IE9 has not installed the Flash add-in, you can download and install the latest Adobe Flash Player by clicking the following Web site.
The third step, if the item shows "disabled", which means that IE9 has installed the Flash add-in, but is not enabled, we simply right-click the add-in and select Enable.
Fourth step, if the add-in displays "Enabled" and still fails to play the video, this problem may be due to a conflict between the graphics driver in your computer and the IE9 hardware acceleration, as we have previously introduced, you can choose to upgrade the graphics driver or turn off the IE9 hardware acceleration function, as follows:
Step Fifth, open IE9, click the Tools icon, click Internet Options, switch to the Advanced tab, find the "Use software rendering instead of GPU" option, and then try again after you check it.
Problems caused by the player software add-in
The above method is limited to solve the use of Flash Player Web site, if the site is similar to Baidu audio-visual, QVOD, PPTV, Thunder and other professional media software video on demand, you need to install these corresponding software.
In general, when we are done with the installation, we will open the IE9 at the bottom of the window to display a prompt box, asking if you want to enable the playback software add-in, here we just click to enable the add-in.
If you have previously installed this playback software, check that the add-in for the player is loaded into IE9 and enabled in the Manage Add-ins tool.
We can check and enable the add-in by using the above method to check the Flash add-in.
If you cannot find an add-in for the playback software, you will need to reinstall the player.
