Hello, I have problem. One day when I started sidbar, it prompted me for locations.msi file, I restarted it, problem persists. So I downloaded Microsoft Windows Installer Cleanup tool and cleared that locations.msi. But now, on every startup of sidebar, Windows Installer windows shows up and closes automatically 2 times, no prompts or messages, only shows and closes, but it significantly slows down startup of Sidebar. Anybody help me, please? Thanks P.S.: Sorry for my bad English...
