I downloaded the installer, but it is not working?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Downloading from the internet can sometimes result in a corrupted download. If the |app| installer you downloaded is not opening, try downloading it again. If re-downloading it does not work, download it from `an alternate location `_. If the installer still doesn't work, then something on your computer is preventing it from running. Try rebooting your computer and running a registry cleaner like `Wise registry cleaner `_. Best place to ask for more help is in the `forums `_.
