I try to update to beta, and get a message that LaunchBox cannot update because the file is in use by another application, such as Dropbox, but my LaunchBox is installed on its own dedicated drive with no backup/restore services, so it should not have any programs accessing it at all. I even disabled malwarebytes and avast just in case, and tried a restart, but nothing works - always the same error. It suggests downloading the latest version from the website to install instead, but I can only download the latest stable release, not the beta. How can I work around this?
EDIT: Just as an added note, when I try to run the LaunchBox-11.10-beta-6-Setup.exe directly (from the Updates folder), Win10 x64 tells me this app cannot run on this PC.
