before each reinstall of sdac3 I have to delete these files manually, otherwise the SDAC 3 installer does not overwrite them (why? I think, at least some message could inform the user, that the installation results won't be good at all

Please, could you delete these files automatically to save us this manual deletion? thanks!
(my os is vista - I find also suspicious, that the uninstaller does not activate UAC. The OS then probably does not allow to delete these files - but why the uninstaller does not at least warn, that some files could not be removed?)
Thanks!
