Question about .dll file

[ronnyfindley]

I'm an idiot, to start.

So, I was downloading Xactimate on a users computer, which is a program that a client uses. So, after download and install, it did not open. It gave me this big error, blah blah. My bright idea was to open another computer with the working program and compare .dll files to see the difference.

So, on the good one, I found a .dll file that was not on the bad one. So, my brain told me to delete it.

...

How do I get it back? Not in recycling bin, and I'm praying the client has server back ups. I'm an idiot.
