Hello, new here. Hope this is the correct place for this question.

I've already downloaded Second Life to my computer, but when I click on it, it's a no go. Instead, I get SecondLife.exe - Unable To Locate DLL. The dynamic link library DINPUT8.dll could not be found in the specified path...

I'm at my wits end. What can I do about this? Thank you in advance for all help.

That serve's a recognition function for direct x 8; go here and update your DX:
