This is a hotfix to fix the Windows installer installing to the wrong place. If you installed v0.20.0 on Windows, I recommend checking if your system registers two separate chaiNNer installs, and uninstalling the extra one after applying this update. If your system is not registering a second chaiNNer instance, I recommend navigating to C:\Users\[your user]\AppData\Local and seeing if a directory called app exists, and if it contains chaiNNer.exe. If it does, I recommend just deleting that app directory entirely. The v0.20.1 installer will not automatically fix this for you. I am very sorry for this inconvenience.
