Hi Ronnie,

How did you deploy the application? Did you use Toolkit or an application package? Please try deploying the application to PowerServer directly by using Toolkit and see if the issue is gone.

Please also check and make sure the following two versions are the same:

1. The PowerServer version.
You can check it from the AEM login page.

2. The application deployed version.
%webserver%/%application%/x32_application.html has line like below.
codebase=\"/appeon/weblibrary_ax/x32/APBPAnalysis.cab#version=12,0,2323,00\">\

Another possible cause of the issue might be the installation of the plugin. Please try to follow the steps below to remove the plugin first and then run the application again:

1 Refer to the article below to remove Appeon plugin from IE.
https://support.appeon.com/index.php?/Knowledgebase/Article/View/55/10/the-steps-to-remove-the-appeon-activex-and-the-components-from-internet-explorer

2 Close all browsers.

3 Uninstall the Appeon multi-browser plug-in from the Control Panel.

4 Run the application on Chrome.

Hi Ronnie;

  Have a look in your PS installation under IIS, as follows:

IE ....

Folder: (ie: "C:\inetpub\wwwroot\appeon\weblibrary_ax\support")

   You should have two files there: "ax_install_x32.zip" and "ax_install_x64.zip". Unzip these into their own separate folder and then run each of their "Update.exe" install programs "As Admin" on the target PC.

All Other Browsers ...

Folder: (ie: "C:\inetpub\wwwroot\appeon\weblibrary_ax\crossbrowser")

   You should have a file there called "appeonbrowser.exe". Run this EXE install "As Admin" on the target PC.

PS: Make sure that all web browsers are closed when installing. Also, a PC reboot might be wise as well after these installs.  HTH
