If you install the Windows installer version of openLCA and set it for "install for anyone using this computer" when you attempt to uninstall, it doesn't work properly. The add/remove programs entry remains and the registry and installed source all stay. This appears to be due to UninstallString in the registry being set to C:\Program Files (x86)\openLCA\uninstall.exe causing it to not realize it should be for all users.
If you actually uninstall with the following, it uninstalls correctly. My screenshots are from version 2.4.1, but this happens on current version 2.5.0 as well.
"C:\Program Files (x86)\openLCA\uninstall.exe" /allusers=1
