XPrint ActiveX Control and Outlook Extension

[Sandy]

After installing the XPrint ActiveX Control and Outlook Extension, we want the XPrint Addin Box unchecked in Outlook > Tools > Options > Other Tab > Advanced Options > Add-In Manager. You can do this manually, but we need to be able to make this change by editing the registry and using SMS

I have identified the registry key that can be deleted and remove the addin altogether. After comparing registry settings before and after unchecking this box in Add-in Manager, I still cannot idenify the switch that controls the checkmark in this box

Any information on registry changes for this utility or the registry key/value that controls this checkbox in Add-in Manager will be greatly appreciated

Thanks
Sandy
