I am trying to provide protection and encryption for some build artifacts that our code produces (The code is written in c++ and c# and we use visual studio) . The tool that I am using is a product called AxProtectorNet which belongs to Wibu-systems company. While doing the protection (using a batch file in which I passed the dlls and the protector tool location) for one dll i am getting the error saying
file protected\Ramin.dll is locked.
I wonder what it means. Does it mean it's already protected? Or is it corrupted? It's worth mentioning that we got the code from another company. So we don't know much about the details on the code.
P.S. I already tried checking if the dll is being used by a process of program etc (through resource monitor)
