Success!
I have managed to have shuffle working in Decor8!
I have Windows 8.1 64 bit. The procedure is given below.
1. First, open Task Manager , and end all processes relating to Decor8. You can activate Task Manager by right clicking on the task bar.
2. Thereafter, open Program Files folder where Decor8 is installed. Create a shortcut in desktop by right clicking on Decor8.64.exe ( or 32 if you have a 32 bit OS).
3. While you are still in the Program Files folder where Decor8 is installed, create a shortcut in desktop by right clicking on Decor8srv.exe.
4. Now you will have to open start-up folder. You can do so by clicking "run" and typing "shell:startup" (without quotes).
5. Now drag the shortcuts that you had created for Decor8_64.exe ( or 32, as the case may be) and Decor8srv.exe to this startup folder.
6. Close the startup folder.
7.Now, the services for Decor8 will have to be made manual from Automatic. For this,open "services". You can do so by typing "services.msc" ( without quotes) in "run".
8. Now search for "Stardock Decor8".Double click on it to open properties.If not already open, click on "General" tab. Now change the startup type from "Automatic" to "Manual".
9. Now click " Apply" and close it.
10. Reboot.
11. Your shuffle in Decor8 should now be working.
