Hello,
Unistalling before you upgrade is not needed. The installer will update the needed information. Not unistalling will help it find the current path and location of the database.
Thanks,

Been doing this for eight years, and that is the first time I have heard anything about installation from AC. Although it may be on the site.
The only issue, is I absolutely abhor the idea of installing databases on a system drive or installing a program on a data drive. Therefore, they have to be moved, which is not best practice.
It would be great if AC had a part in their install where you could decide where to install the program and where to install the databases.
By the way, you have to use the tuner whether you uninstall or not. I don't know why the tuner can't be incorporated into the installer.
