I am trying to uninstall Sibelius on my friend's laptop, but there is no uninstaller file (according to the registry and add/remove programs). However, Sibelius is undoubtedly installed as system restore detects it (though it fails to undo the installation), and it can run. If I run the 8.2 installer, it says there is already a previous version installed and won't proceed. Could someone possibly upload their own uninstaller file for me?
I had a similar experience with uninstalling Sibelius on my mac recently. Unable to find an uninstaller, I held my breath and moved it to the trash. There was a warning that some files might possibly be lost, but I went ahead and it worked a treat. I also note that Clean My Mac 3 (free trial version) does uninstalls. Not sure about PCs.
