Program does not start up error reads The dynamic link library PEGRPDS.DLL could not be found in the specified path.....L:\softrak receivables c|winnt....so on so on....

I installed this as per usual on a computer in the server room it updates the files on the server, as I have for all installs then go around and do the workstation upgrade on the 3 accounting computers, but it comes up with this error.
