Actually this is not an issue or bug, it is not even directly related to ADFdi. Everything work as supposed to 🙂
ADFdi plugin can’t function properly, because Excel opens file in a protected view. This happens because AES (Attachment Execution Services) marks file as downloaded from internet (only MS IE and Outlook can do this). Before showing file contents Excel checks AES records and automatically switch to protected view.
- Disable protected view for files downloaded from internet ( [Open Excel] -> File -> Options -> Trust Center -> Trust Center Settings -> Protected View -> [Uncheck “Enable Protected View for files originatin from the Internet”])
- Change Windows OS localhost real location (sounds like a hack). To accomplish this – open windows hosts file (sample location: C:WindowsSystem32driversetc), add record “[application servers, where resides Excel file, IP] localhost”
- Some other
