This program seems to be just a standalone installer for D2D.
The executable is just an archive. If you have a WinRar or similar program, right click on the executable, and in WinRar menu select "Open With WinRar". You will see what's inside. You can also extract all the files to a separate folder and run setup from there. You will see that there is nothing Dell-specific there. Just updated version of D2D 9.
I was able to install it on XP (Compaq laptop) and Vista (Sony laptop).
BTW, despite my initial excitement about burning applications in Vista they do not seem to be good at all. If you create a 'Mastered' disc, you need twice as much free space as the amount of data you are going to write. Also when it writes VIDEO_TS folders, it ignores the information in .IFO files. Recording program shoud either place files on DVD according to what it reads from .IFO files (as RecordNow, aka 'Home' does), or alter .IFO files to reflect file positions on disc (as other programs do, e.g. ImgBurn). Microsoft's software doesn't do either, so DVD players do not recognize the resulting disc. . Packet writing seems to be OK (no BSOD, which is already good), but when it formats DVD+RW disc, you only get about 4 GB of space, while D2D gives you 4.3 GB. So it looks like Roxio will stay for the time being.
