I have created add-on and deployed it on 40 PC's. It works on 38 PC's but on two PC's it gives error as,
Wrong executable digital signature for Add-on
First problematic PC is having windows 7 and another PC is with low configuration. I searched on forum and I found solution that releasing new version may fix this problem. But the problem is not fixed. I am deploying add-on since 5 years and I follow the same procedure. Now the senior people say's your deployment procedure is wrong.
