After you install a previous version of Flash Player, movies don't appear in the browser as expected. Sometimes, you receive the following error:

"Object doesn't support this property or method."


Do one of the following:

Solution 1: Install Flash Player or later.

Download Flash Player or later from the Flash Player Download Center.

Solution 2: Manually remove the "kill bit" registry entry.

Important: Adobe does not recommend manually editing the Windows registry unless you are already familiar with the Windows registry editor. Proceed with caution, and only if you feel confident changing the registry. Incorrectly modifying the Windows registry can result in serious Windows or application performance issues. Adobe Technical Support cannot be responsible for problems caused by modifications made to the Windows registry.

Note: If you are not comfortable editing the Windows registry, there are third-party applications available that can edit the registry. Spyware removal applications sometimes have tools that look for Flash Player registry entries and remove unnecessary items.

To manually remove the "kill bit" entry from the registry, look for the following registry item:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility\{D27CDB6E-AE6D-11CF-96B8-444553540000}\

Make sure that this registry item doesn't contain any strings. If there is a string value, it is most likely a set of compatibility flags, as shown below:

Registry editor


This entry causes Flash movies to fail in the browser. Delete the compatibility flags entry and restart Internet Explorer.

Alternatively, you can also set the Value data to zero for Compatibility Flags.

Double-click Compatibility Flags. The following dialog box will appear:

Set Value data to zero and Click OK

Set Value data to zero and Click OK.

Additional information

A "kill bit" entry in the Windows registry causes this error.  Ad and pop-up blocker installations usually create this registry key. Uninstalling the pop-up blocker doesn't necessarily remove this registry entry.
