When digitally signing with ArcGISSignAddIn.exe of Pro, Although you can sign it, if you install and run the add-in, it will not work properly.
The cause was that the file name was broken in the middle and broken when including the geodatabase in the add-in. Is there a workaround? I want to grant a digital signature without file loss, Is there a way to sign other than using ArcGISSignAddIn.exe?
