For security reasons new builds of Microsoft Office for Microsoft 365 on Windows block activation of Flash, Silverlight, and Shockwave controls. Most users won't be impacted, but for some users this may cause one of the following issues:
How do I get silver light to work on my computer with windows 10 I have microsoft edge not internet explorer. Hi, Edge does not support Silverlight. Microsoft Silverlight may not be supported on your computer's hardware or operating system. RECOMMENDED: Use Silverlight in the 32-bit Internet Explorer process on x64 systems. Most browser plug-ins (including Silverlight, Flash, Java and almost all ActiveX controls) only work in. Silverlight will reach the end of support on October 12, 2021. Silverlight development framework is currently only supported on Internet Explorer 10 and Internet Explorer 11, with support for Internet Explorer 10 ending on January 31, 2020. There is no longer support for Chrome, Firefox, or any browser using the Mac operating system. Support for Silverlight has been removed in Microsoft Edge. But Microsoft continues to support Silverlight and Silverlight out-of-browser apps can continues to use it. Silverlight will also continue to be supported in IE 11.
When you click on an embedded Flash movie in PowerPoint Slide Show, nothing happens even though this worked before.
Power View in Excel does not work anymore (because it uses Silverlight). You may see an error message that says 'Activate method of OLEObject class failed'.
Flash content is displayed as a blank page with an X when you click a folder that has the folder homepage set in Outlook.
RECOMMENDED: Use Silverlight in the 32-bit Internet Explorer process on x64 systems. Most browser plug-ins (including Silverlight, Flash, Java and almost all ActiveX controls) only work in 32-bit browsers currently.
Unblock these controls by editing the registry
Caution: Follow these steps carefully. Serious problems may occur if you modify the registry incorrectly. Before you start we recommend that you have a known good backup of your registry. See this article for more information: How to back up and restore the registry in Windows.
Exit all Microsoft Office applications
Start the Registry Editor by tapping Start (or pressing the Windows key on your keyboard) then typing regedit and pressing enter.
Locate the proper registry subkey. It will be one of the following:
HKEY_LOCAL_MACHINESOFTWAREMicrosoftOffice16.0CommonCOM Compatibility
(for 64-bit Office, or 32-bit Office on 32-bit Windows)or
HKEY_LOCAL_MACHINESOFTWAREWOW6432NodeMicrosoftOffice16.0CommonCOM Compatibility
(for 32-bit Office on 64-bit Windows)Note: The COM Compatibility node may not be present by default. If you don't see it, add it by right-clicking the Common node and choosing Add Key.
Add a new subkey with the CLSID of the control you want to unblock as the value by right-clicking the COM Compatibility node and choosing Add Key.
Control
CLSID
Flash
{D27CDB6E-AE6D-11CF-96B8-444553540000}
{D27CDB70-AE6D-11CF-96B8-444553540000}
Silverlight
{DFEAF541-F3E1-4c24-ACAC-99C30715084A}
Shockwave
{233C1507-6A77-46A4-9443-F871F945D258}
Note: For Flash you'll need to add two subkeys, one for each of its CLSID's.
Within that new subkey we're going to add two new values by right-clicking the new subkey and choosing New > DWORD (32-bit) Value.
A REG_DWORD hexadecimal value called Compatibility Flags with a value of 0.
A REG_DWORD hexadecimal value called ActivationFilterOverride with a value of 1.
Exit Registry Editor and start your application. The control you need should be unblocked now.
Example
For example, to unblock Silverlight in order to get Power View working in Office 2016, 64-bit, on Windows you would locate this registry key:
HKEY_LOCAL_MACHINESOFTWAREMicrosoftOffice16.0CommonCOM Compatibility
Note: Remember, if the COM Compatibility node doesn't exist yet you'll need to create it.
Then add a subkey with the value {DFEAF541-F3E1-4c24-ACAC-99C30715084A}.
In this case, the resulting path is HKEY_LOCAL_MACHINESOFTWAREMicrosoftOffice16.0CommonCOM Compatibility{DFEAF541-F3E1-4c24-ACAC-99C30715084A}.
To that subkey you'll add a REG_DWORD value called Compatibility Flags with a value of 0, and a REG_DWORD value called ActivationFilterOverride with a value of 1.

Silverlight Supported Browsers
Compatibility Add-on for Chrome or Firefox
There is a free browser extension called 'IE Tab' that runs Windows Internet Explorer (IE) components within a tab in Chrome or Firefox. This enables you to display web pages that use Silverlight (such as CTI Navigator Web) within your Chrome or Firefox browser, even if the browser itself does not correctly load Silverlight. The IE Tab also includes an 'Auto URL' filter and a Bookmarks feature that allow you to specify which URLs should always be loaded with IE Tab.
Silverlight Support Windows 10
Even though it does not open the IE browser per se, IE Tab uses the IE Browser Control core engine. Therefore, to ensure full security when using IE Tab, the latest version of Internet Explorer should be installed on your computer and it should be kept up-to-date with the latest security patches from Microsoft.
You can read about and download IE Tab at www.ietab.net.
