Error on CTP addin helper

[Oscar Peters]

Hi all,

I have created an add-in using Excle-DNA that uses a Custom Task Pane - it works on my machine :-). However, when I want to use the add-in on a corporate machine with (granted) stricter security settings, I get an error, see first attached image. Turns out that a setting in the trust center seems to be the culprit, see second image.

The thing is, the rest of the addin works flawlessly, the ribbon and algorithmia, but only the CTP does not show. From the error message I learn that it has to do with the helper add-in that is created for the CTP.

Why does this only happen for the custom task pane? Can it be resolved? At this stage of development I don't want to go down the rabbit whole to get a signed trust certificate. Too much hassle and takes to long to get it.

Are there any resolutions for this - other than unchecking that checkbox?

Kind regards,

Oscar Peters
