The latest version of Hamachi appears to be buggy as it has caused a number of our hamachi client installations to malfunction over the past 3 days. This was as a result of the automatic updates.
For instance, some cases, the Hamachi virtual ethernet adapter fails to install. In other cases, the color indicators (i.e., green, red, cyan, etc.) disappeared. In yet other cases, a yellow triangle with an exclamation has appeared at the end of all systems. This is a really buggy update. Hope they fix all of its issues soon as it is causing big problems for all our users.
