GEM is running in Internet Explorer only.
The only browser, where GEM is working, is Internet Explorer (IE), because “Active X components" must be allowed for GEM/GRM and it is possible only when Internet Explorer browser is used. If your PC was upgraded and IE browser is not available anymore, you will receive following warning.
In the attachment you will find the procedure, how to use IE in Edge.
We have already developed a new GEM called TCP Exchange that doesn’t need IE and is running in other browsers, such as Google Chrome, Edge, Firefox etc. Please contact your country manager and discuss TCP Exchange registration with him/her. All Travelport country managers have been already notified.
