Before the installation starts, the installer will check whether you have an older version of the software already installed. The following dialog will appear if a previous version has been detected:

Clicking
Ø Yes; will migrate previous settings and uninstall the previous version. Previous settings include library files, window layouts, units, colours and custom toolbars.
Ø No; will allow you to have the old version on your system as well as the new version.
Ø Cancel; will abort the installation.
Note
The installer will not uninstall versions older than
- version 10 for Multiframe
- version 13 for Maxsurf
If older versions are detected in the C:\Program Files\Maxsurf or C:\Program Files\Multiframe directories respectively, settings will be automatically migrated to the new installation. If you have previously installed into a directory other than C:\Program Files\ then you will need to manually copy your library files to the new installation directory.
