Quote - I didn't had to. I did it from years of experience, never rely on an uninstallation routine. No reflection on DS, this goes back to before DS. Things are better now, but old habits die hard.

 

I have both DS4 32 and 64 bit versions installed. I use the 64. I am guessing I will need to uninstall both and the present DS default content and the content management service then install 4.5 64 bit followed by the new default content?
