Do end users need Windows administrator rights to allow ActiveX? Do they also need administrator rights to download the application's elements (first deployment)?

1.       If you are using IE 8 on Windows Vista or Windows 7 OS you DO NOT need Windows administrator rights.

2.       If you are using Windows XP or non-IE 8 browser (for example IE 7 or IE 6) you need administrator rights to load the ActiveX. 

Alternatively, the system administrator could deploy the ActiveX manually instead of granting the user the access.  We provide the ActiveX as a .MSI file so that the system administrator can deploy that the same way they deploy Windows service packs.

The .msi file that would install the Appeon Xcelerator plug-in ActiveX control is included in the Appeon product.  It can be found in C:\inetpub\wwwroot\appeon\weblibrary_ax\support

Please note that even if you can install msi silently you still need to give it permission to be run in IE;  in other words, you cannot silently install the MSI file completely without enough permission.
