If you previously had the trial version of DeskScapes installed you will want to remove it first. Installing the full version over the trial will not overwrite all the files from the trial version. You must uninstall the trial (or any full versions installed over the trial) and reboot the machine before installing the full version.
You will first want to go to Start->Start Search and type services.msc. Once there, be sure the Desktop Window Manager Session Manager service is running and the startup type is set to automatic.
The most common issue with DeskScapes not running is not having a Windows Vista Experience rating. This is how Windows Vista determines if your machine is able to handle the visual enhancements build into itself, and many of the options will be disabled or run with limited functionality without it. To run the Windows Experience Index rating, right clicking on "Computer" and select "Properties". Once you do this, click on the "Windows Experience Index" and in the dialog that comes up, select "Update my score". This will make Windows Vista update your rating and should allow you to apply the Aero theme, as well as run your application correctly (If you have Vista Home Basic, the "Windows Vista" theme will also work).
To make sure the correct theme is enabled:
-Right click on your desktop, choose personalize.
-Click on Themes
-From the drop down menu, choose 'Windows Vista", then click apply and ok. (NOTE: If you have WindowBlinds themes applied, you can reapply them after this.)
If that still does not allow you to display .dreams, please try the following:
-Click the Start orb
-Right click on Computer, select properties
-In the tasks pane on the left, select 'Advanced system settings'
-Click the 'Settings' button in the 'Performance' section
-Check 'Enable Desktop Composition' from the list
-Click 'Apply', then 'OK'
-Click the 'Settings' button to be sure that is still enabled. If it is not, please go back and make sure that the Vista theme is set by the instructions above.
If .dreams files will still not play, and you are not getting the Desktop Window Management service not running error, you may need to install a mepg2 codec. Here is the Microsoft information page about codecs:

We recommend if you are unsure about what codecs you have installed using the following tool to find out:

If you do not have Vista Home Premium or Ultimate installed you likely do not have a codec. There are many third party codecs available. During testing we found that the codecs bundled with Cyberlink PowerDVD Ultra, and DX for Windows Vista appeared to be compatible with video dreams.
