Run Previous Version
Problem: You installed a new version and there are problems with it.
Solution: Use a previously installed version.
When you install a newer version, the previous versions are not removed. Here's how to create a shortcut on the desktop to a previous version. In this example, there are two versions installed 2016.0621a and 2016.0819. If you want to run a version that is not installed then you need to download it and install it. This video only covers the case of running a version that is already installed.
