Due to the Data Execution Prevention (DEP) feature in Windows operating systems, any
ActiveX control built with ATL version 7.1 or earlier will fail to host, or will behave
unpredictably in InTouch, either in WindowMaker or WindowViewer.
The ActiveX controls and error message, along with solutions to resolve the behavior,
are described in detail in TechNote 522, "Some ActiveX Controls NOT Supported in InTouch 2012 R2 (Version 10.6)". You can
download this TechNote from the AVEVA Global Customer Support (GCS) website.
