The default installation directory is the same as for Readerware 1.x. Therefore Readerware 2.0 will replace your current installation. If you want to keep both versions on your system, pick another directory during installation.
There are a couple of issues that might impact some users.
The database format has changed in Readerware 2.x. The conversion is automatic, when Readerware opens a database it detects that it is still in 1.x format and converts it. This conversion is a copy process, it builds a new 2.x database and leaves the existing 1.x database. However they share the same images directory so you should not continue to use Readerware 1.x after installing Readerware 2.x.
If you have several Readerware databases, they will not automatically show up in the Readerware open dialog. By default Readerware only displays 2.x databases. To open a Readerware 1.x database, change the file type drop down list at the bottom of the open dialog to select Readerware 1.x databases, you will then be able to open and convert the database to the new format. From that point on you should open the 2.x database, which will automatically show up in the open dialog. You will need to repeat this for all your Readerware 1.x databases.
While your there on the File menu, please notice the new Backup Database menu item. This is a very easy way to backup your database, Readerware will create a single ZIP file with your complete database and all the image files. As everything is backed up to a single ZIP file, you can easily archive your database for safe storage. Take a moment now and backup your new Readerware 2.x database.
As always, I am here to help. If you have any problems installing Readerware 2.x or upgrading from 1.x please contact support@readerware.com.
