of Windows Installer are you running? There is an update here http://www.microsoft.com/downloads/details.aspx?familyid=889482fc-5f56-4a38-b838-de776fd4138c&displaylang=en
I'm getting a message that programs will not install. It downloads the program but it won't then install it. Instead a message pops up saying windows installer can't install the program and this could be because the install program is either not properly installed or it's running in safe mode. As far as I know it is not running in safe mode and I have not reinstalled the installer. Why would I get this message? How can I fix it?
