Usually, the new version overwrites the previous one.
From 2015.07 on, DDB Access uses a different install path and installation wizard. As a consequence, the older and newer versions may both be present:
|Before 2015.01:||C:\Program Files (x86)\DDB Access|
|After 2015.07:||C:\Program Files (x86)\SmartHanzi\DDB Access|
If the upgrade seems to have failed, it may just mean that the older version is still present.
To make sure that older versions are correctly removed:
- Check if C:\Program Files (x86)\DDB Access is still present.
- If yes, doubleclick 'Uninstal' (or 'Uninstal.exe') in C:\Program Files (x86)\DDB Access.
- Download and install the latest version.
