IE10 wants to run add-on 'GPAX' from 'ENST (unverified publisher)' RRS feed

  • Question

  • I'm developing a website that uses HTML5 and SVGs. It renders fine in Chrome, Firefox, Safari etc. In IE10, a message pops up asking me if I want to "run the following add-on: 'GPAX' from 'ENST (unverified publisher)'.

    I can't find any references to GPAX or ENST anywhere. Why does it show up and is it safe to allow it?

    Much appreciated.

  • Hi,

    Please post questions about html, css and scripting to the MSDN IE Web Development forum. Include with your question a link to your website for investigation and analysis.

    MSIE browsers instantiate ActiveX controls with either the <object> tag or use the scripting of the ActiveXObject.

    You can use the Debug tab of the Developer tool (f12>Debug tab) to search your markup and scripts for <object tags or the use of activeXObject in your or third-party scripts that you have placed in your pages.

    "In IE10, a message pops up asking me if I want to "run the following add-on: 'GPAX' from 'ENST (unverified publisher)'."

    It must already be installed on YOUR computer... Tools>Manage addons>Show All Addons to search for it in your IE Addons manager.... double click on the item in Addons Manager list to display its property page.

    Click the "Search for this addon using your default search provider" link in the Properties page to find the Publishers website for the addon.

    mmm.... I think you mean GPAC


    GPAC officially started as an open-source project in 2003 with the initial goal to develop from scratch, in ANSI C, clean software compliant to the MPEG-4 Systems standard, a small and flexible alternative to the MPEG-4 reference software. GPAC can probably be seen as the most advanced and robust 2D MPEG-4 Player publicly available worldwide, as well as a decent 3D player. 3D support is available on embedded platforms through OpenGL-ES 1.x.

    so after all that... you must be using the <video> tag... simpler just to post YOUR url?
