As often a solution to a strange error is so simple when you know it. When I copied my add-ins to a new computer I was not able compile the objects that included DotNet add-ins.
As this happened when I was installing NAV 2013 R2 for the first time my first thought was that this was something that had changed between versions and I sent a support request to Microsoft.
Mohamad Vajid and Duilio Tacconi took the case and tried to reproduce the problem without success. Yesterday we took a look at the problem together and the solution came to our attention.
The Add-in was copied from a web site and because of that the file was blocked by the server operating system.
Then today as I was creating a new website with files that I downloaded from the web I had the same problem. That will be the last time.
After you unblock the file, recheck to see if that worked. If the file is in a protected folder you might need to drag it to your desktop to unblock it and back again.
Thank you Mohamad and Duilio for the assistance.
I reported exactly this problem back in june to microsoft and I got the solution after a few weeks. It should be a known issue.
Thanks Gunnar.
Being a dotnet lightweight. I wondered what I was doing wrong, then found your solution.

I hit this problem as well, and the solution I used to fix it was streams.exe that can be downloaded from technet:

Thank you.
I am now using powershell to make sure none of the files are blocked.

Hi, I’m having the same error message occur with NAV 2015 and an add-in I’ve created. I have been developing an add-in and so far, all was working well. Now, for some reason, the error message appears. There is no option to unblock.
Any ideas?
TIA
Chris
A Client Add-in might need to be recompiled with the UI Framwork from the 2015 DVD. Is that the case here ?
Hi,
Thanks for the reply. It is using the UI Framework from the 2015 DVD. The add-in was working fine in 2015 but it is constantly under development at the moment and for some reason just stopped working in NAV. I am going to try the latest CU of 2015 and see if that makes a difference but I am not hopeful.
Cheers
Chris
