We have received reports of an Unsupported Browser error when previewing files in DMF and after investigation we have discovered that this is due to an issue with Windows Internet Explorer 11 which we use to display the preview. Unfortunately this is beyond our control but we have implemented the use of Microsoft Edge WebView2 in DMF 8.9.784 or later.
WebView2 uses Microsoft Edge as a rendering engine to display web-based features in a desktop application. For more information on Microsoft Edge WebView2 please click on the link below:
Resolution
1. Please download and install the latest version of DMF 8.9
2. Please download and install Microsoft Edge WebView2
After successful installation of the applications mentioned above the DMF preview issue will be resolved.
