Beginning with Qlikview May 2023 (12.80), QlikView documents cannot be opened using the Desktop AccessPoint with the IE-Plugin. See QlikView: Tool's Menu.
The following prompt is displayed when attempting to open the AccessPoint:
Reload this page in Internet Explorer (IE) mode to access the plugin
Resolution
Two workarounds are available.
Use AJAX to open the AccessPoint
Open Favorites & Profile accessible in the top right
Set the Preferred Client (a) to the Ajax client (b)
Use Microsoft Edge to open documents directly in the Qlikview Plugin
Starting with QlikView May 2023, the rendering engine was changed to webview2, which does not support OCX-objects, the underlying technology used to embed the QlikView Plugin in a browser.
