Blocked add-in files after copying CU-files to an existing NAV installation

Have you ever had problems with add-in’s after you have copied files from a CU to an existing installation? The reason can be that the dll’s are blocked since they are downloaded from internet to your local hard drive. Windows keeps track of zone information as meta data linked to each file and block the files by default. There are a couple of approaches to solve this problem:

  • Unblock an individual file by right clicking the file and click the checkbox to unblock.
  • Open Windows PowerShell or an elevated Windows PowerShell depending on if your user account has access rights to where the folder containing the blocked file(s) is located and execute this: get-childitem -recurse |Unblock-File
  • Completely disable the zone blocking ib the gpe:

Happy updating 🙂
