Converting a msi file from windows to work on IOS MAC -- 2

We use an online programme for booking in orders to a courier. This we do through our website directly with palletforce. When we log into palletforce we then need to just print the labels. However, to open the file to print the system needs to run a small MSI file. This works on a PC but on a MAC MSI files do not work. We need someone to convert what is on the MSI file to work on a MAC so we are able to print the labels. copy of the file attached Many thanks James
