I just got a ThinkPad T510 with Windows 7 Professional and I installed Daemon Tools Lite, but I keep getting an error when I run it:

Unable to add adapter.

I can't load iso images, because there is no virtual drive. I tried starting it as an administrator, it tried to update the virtual devices, and it got the same problem. Does anybody know how to fix this?

OK, here is how I solved the problem for Windows 7:

  1. Uninstalled Daemon Tools.
  2. Uninstalled SPTD.
  3. Removed legacy SPTD keys from the registry.
  4. Re-installed SPTD before installing Daemon Tools.
  5. Installed Daemon Tools Lite.

Here are the resources that I used:

  2. This shows how to clean up the SPTD registry keys and install SPTD by itself (without Daemon Tools):
  3. You can download the latest SPTD by itself here:

Thanks for that, although you might have gone a little overboard. Windows 7 64-bit - All I had to do was install the latest version of SPTD (64-bit) manually, then re-install Daemon Tools and the problem was solved. No messing around in the registry needed. – user56382 Nov 21 '10 at 17:48
