Once you have purchased you will receive access to the ListMailPRO files. Save the file, ListMailPRO_v1.23.zip (for example), to a folder on your local hard drive. I like to create a directory C:\DL for all of my downloads so I can access them quickly. You could also use C:\TEMP, which might already exist, or your Desktop.
Unzipping the Distribution File
If you don't already have the common utility WinZip, you can download it from WinZip.com. It will allow you to get at the files inside the distribution package so that you can start setting up ListMailPRO.
When running the WinZip setup program, you can uncheck the options to install icons anywhere. This is because you can simply right-click on a .zip file in Windows Explorer to access a quick extracting link.
Once WinZip is installed, right click on the zip file in Windows Explorer and choose Extract (to the default folder). This will create a sub folder within the current folder with the same name as the zip file. Double click the folder to open it.
