Default How to detect if a DLL is installing

Hi, all experts,

I create a DLL that not marked as safe(just for internal use),when user first time run my program, the popup window will ask him if he allows to install a unknown producer Dll file. Depend on computer, some time this process is fast, some time is very slow. If slow, client will get confused and don't know what's wrong.

My questions are:

1: Is there some way that I can check if the client computer already install the DLL or not?

2: While installing, it will also take time, how can I detect if the DLL is in the process of installing? If I can detect, I wish to tell user that it's in the process of installing.

3: Because this DLL is not marked safe, so user has to change computer security setting to download this DLL, can I detect(not change) user computer's security setting?

4: Is there a free way to create a DLL as safe?

Thanks a lot!
