K question - I have created a working dll and custom indicators on my computer, everything works correctly.

I sent a copy of the dll and formulas to a friends to use. He has the same version of MS as I do. And this isnt the fist time we have done this swap. He has placed the dll in the correct sub folder and has imported my formulas into MS But for some reason MS is not picking up (reading the dll) it say it does not exist within the folder and when we look for it in the Indicator builder its not there.

So for some reason MS is not picking up the dll when he opens MS. Has anyone had this same problem as us? If so how did you correct it... Any suggestions?
