Hi, We have an issue where our RTM msi had some launch conditions that are preventing patches from being uninstalled. It was suggested that we create a uninstallable patch to remove that launch condition so that subsequent patches could be uninstalled.
This seems like a simple thing to do, but I am new to patches and don't know where to start. How do I go about authoring a patch to remove launch conditions?
