Issue

You need to disable the MySQL service.

Solution

Open your Control Panel. On the top right, change the View By dropdown menu to Small Icons:

Click Administrative Tools:

Click Services:

Scroll down through this list, and double-click on MySQL:

Now select Disabled from the pull-down menu and click Stop:

Have you moved your LandFX folder to a shared online location using a service such as Dropbox?

If so, you'll need to rename your folder. Navigate to the root of your C: drive in Windows File Explorer, and rename the LandFX folder to Landfxold.

 

That's it! Your old Single-User installation is now turned off and won't cause any conflicts.
