Plugin not loading(NETLOAD)

[Anonymous]

Hello guys,

Please help me, I've been creating a plugin(with C#) with MVS 2012, and testing it at CAD 2015, it works fine...but when I sent it by email to a friend( he has CAD 2016), he tried to load my plugin(NETLOAD), it's not working at all, but a few time ago I went to his home with my plugin into a pendrive, it worked easily, what could it be? (since this problem I've been trying to test the same plugin that I send by email, downloading it to my computer again sometimes it works some times CAD returns this message)...I tried load my plugin in two diferent computers...same problem...

Cannot load assembly. Error details: System.IO.FileLoadException: Could not load file or assembly 'file:///C:\Users\Péricles Jr\Desktop\latest.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)

When you send a DLL via email, or download it from a site, Windows 'Blocks' the file. Find the file in Windows Explorer, right-click, select Properties. On the General tab, towards the bottom, you will likely see a button labeled Unblock...click it.

Thanks friend, it worked.

But now I have another question, how do I configure my code (if it's possible), to make windows stop blocking my plugin?

Thanks in advance.

If you create an installer for your plugin, then it typically does not get blocked by Windows. I use Inno Setup available for free here: http://www.jrsoftware.org/isinfo.php There are others, I'm sure, but this has worked well for me.
