Hello. I am installing Micropay Professional 2013 on 3 client computers and a server. The server installation was fine and it is running v14.4. However, When installing the client computers, when I click on 'Select Data Drive' a dropdown menu appears and wants me to select the drive the data is on. I have sucessfully mapped the Data Drive as you can see below:

But when I click on the dropdown menu, there is no Z: drive there and I tried scrolling but it simply shows my media inputs (SD card slot, etc).
My guess is that the install software does'nt like network locations due to the fact that we have installed v14 before and it choked up on upgrading to 14.4 and I have tried to create virtual drives via the cmd command subst.
Any help will be greatly appreciated.
