If you have the "download only" version of the program:

First download the latest version by clicking here to get the latest DTDsetup.exe file and save to your hard disk.

Get the new license key file installer from us (go to Buy DTD to purchase an upgrade key installer)

Simply uninstall your existing version of DesktopDoppler

Then install the new version of DesktopDoppler from the downloaded DTDSetup.exe  file you saved on your hard disk

Then run the license key installer, which will copy and overwrite the DesktopDoppler.vpl license file in the

C:\Program Files\Personal DesktopDoppler folder,

if you installed DTD to a different folder location on your disk or another disk, you will have to locate that directory and point the installer there so that it can update the license key file.

Finish the license key installer and then run the DesktopDoppler program.

-or-

If you have the CD ROM version of the program:

Uninstall the previous version of DesktopDoppler

Then simply run the installation program from the CD to install the new version.

That's it!
