Important Note about installing a new version

In order to avoid problems you must follow these steps when you install or register a new version of the preview handler.

1. Close all the windows explorer instances which have the preview handler active or the preview handler was used (remember the dll remains in memory until the windows explorer was closed).
2. Unregister the previous version executing the uninstaller located in C:\Program Files (x86)\TheRoadToDelphi\DelphiPreviewHandler or C:\Program Files\TheRoadToDelphi\DelphiPreviewHandler
3. If you install the preview handler manually you must unregister using the UnRegister.bat running as admin.
4. Now proceed with the installation of the new version.
