I have created a set up project to deploy an esri addin. I have used this tutorial ArcObjects 10 .NET SDK Help I am using Arc10.2.1. I use this regkey: SOFTWARE\Wow6432Node\ESRI\Desktop10.2 instead of ' SOFTWARE\ESRI\Desktop10.2' mentioned in the above link. When I try to use the set up.exe i created, I get this error 'ArcGIS Desktop 10.2 is required before you can complete this setup.' while the target machine has ArcGis desktop 10.2 installed. Any help will be appreciated. ... View more

I have changed the selection symbol of polygons feature layer.I have also added an annotation layer above the polygons layer. but I have found that annotation layer is hidden under the selection symbol though it is added over the polygons feature layer. I have also tried to make the color of the fill symbol of the polygons transparent.but the annotations are hidden under the selection symbol as well. see attached images. ... View more
