If you would like to remove the DataVeil settings and cache folder please open the GUI, choose Help->About and make a note of the folder locations User directory and Cache directory as shown in the example below:
Close (stop) the DataVeil GUI and then delete the two folders.
Now you can proceed to uninstall the DataVeil software. Simply delete the folder where the software was extracted (i.e. the unzipped folder from where the software is launched).
This will have completely removed DataVeil from the installation computer.
If the DataVeil Native Library has also been installed on DBMS(s) then you shall need to uninstall those too. The uninstall instructions can be found in the Native Library section.
