DLL is missing

When i open JJsploit it always says: update. When its done it says: "Update downloaded. Please look for the installation window. Otherwise re-download from wearedevs.net if there any issue" I dont know what to do here, so i just re-open when i did that it says: "Could not find DLL! Please re-open JJsploit and wait a few seconds for it to atomatically download. (He updates it everytime i open JJsploit) Disable your antivirus if its deleting DLL" Well i dont know 100% if i did that right so can you say how? And how i fix this. When i re-download JJsploit it wont help.
