RemovePreviousVersions doesn’t work in VS 2008

I’ve deployed my program from VS 2005 for about 2 years now and updates have worked just fine with VS Setup deployment project.

When I increment my version number from 1.0.50 to 1.0.51 the reinstallation seams to go fine but it doesn’t replace the new dlls and exe files in the installation dir…

If I uninstall an then install it works fine but I don’t want my users to do that every time I release a new version.

RemovePreviousVersions = true
DetectNewerInstalledVersion = true
