If you are proficient at installing Miva Merchant modules the only thing you need to know is to logout of admin after install, and then login again to see the changes.
If you are new to installing modules, use these step by step instructions.
If you havn't already downloaded LaunchPad Click Here.
The LaunchPad download is a "ZIP FILE" called launchpad.zip. This is an archive file which contains LaunchPad and help files. Before you can install the module, you must "extract" it from this zip file to a place on your computer where you can find it, for example the DESKTOP. Extract the files launchpad.mv and launchpad.mvc and follow the directions below.
Add Module
Adding any module to Miva Merchant needs this step. Open the Modules menu tree and click Add Module
Click the icon show. This kicks off the part of Miva Merchant that can upload files from your computer.
If you were UPDATING or UPGRADING a module, you would check the Overwrite checkbox. Click Browse and locate the module file that you downloaded from MivaCentral. The file is either launchpad.mv or launchpad.mvc. The easiest way to know which one you need is to look at your Admin url and match the extension:
ie:
admin.mv? Use launchpad.mv
admin.mvc? Use launchpad.mvc
When you've located the file on your computer click Upload
The previous step will upload the file to your server. Now click Add
