indolence

Already read through this thread, and didn't see my problem listed: http://forums.getpaint.net/index.php?/topic/692-install-update-or-uninstall-trouble-read-this/ I'm getting the following message, with no error number: Windows XP SP3, or Windows Vista SP1, or newer is required. I'm on Vista. As far as I can tell, you can no longer update to a specific service pack, but I'm fully updated through Windows Update. I don't have issues with any other programs I've tried to install. Any ideas?
