Click the main menu in the top left corner and select Settings
Navigate to Projects, Central Projects - Local, then select Change
Default location type 1
C:\Users\[username]\AppData\Local\ARANZ Geo\[x]\[y]
Where
[x] could be one of the following Geo, Works, Geothermal
[y] will be the slightly different depending on the prior version of Leapfrog you were running e.g projects_6.0.5
Default location type 2
C:\Users\[username]\AppData\Local\Seequent\Leapfrog\projects
If the folder fits the default location type 1 format, your default location is as expected. You can select close, your projects should be showing, there is nothing further to do.
If the displayed default location is in the default location type 2 format, you will need to manually select the default folder, setting it to the type 1 format mentioned above, by following the below steps
A message "The selected folder is not empty" may display, it is safe to select "yes" on this option.
You can now navigate back to the home screen and refresh your view, your projects will now appear.
Alternatively if your default location does not match the type 1 or type 2 formats, you can also select close, your projects should be showing.
